Well I changed my entire microtech map to one from the "microtech thread" on stock tII turbo and the car still will not start. Using ether, If I get it to run it just wants to make a horrible noise from the rotors and then shut off. I think the engine is getting too much fuel or not enough. I have to check my fuel pressure regulator today to see if it is at 43 lbs or not.

 

keep plugging away you will get it. i just got my 1970 rotary bug on mega squirt to run. what are your AFR's when it starts up? if your between 12:1 - 15:1 it should start and run. not ideally until it stableizes around 13.5:1 ay idle. did you solve the white smoke issue? did it smell like fuel at all?

first start of my bug WAYYY too much fuel . AFR around 8:1 and had some spark settings messed up.

then after plugging away on the computer and fixing an injector issue.

its very rewarding when she runs correctly, good luck.

 

The smoke has gone down to almost none, smells like a two stroke now, which is good and I don't think there is any more oil or water leaks cause the smoke is perfect for my standards. My AFR does some weird stuff. I do smell fuel coming from somewhere... Right now Im going to check my fuel pressure regulator and the fuel line to see whats going on. What values did you change wankel bug to make the AFR change, I fucked up my first base map in the micro by trying to to change settings which inevitable didn't change my afr

Bug runs great in second vid! way to go! *muttering lucky bastard behind gritted teeth* haha

 

luck is relative, the harder i work the luckier i am.

first off if you have a fuel leak stop everything and fix it. fires fueled by 40+ psi of gas are not cool.

so many variables to pick a place to start diagnosing the issue. what O2 setup do you have? is it the microtech o2? after my first run i pulled cleaned and re calibrated my o2 sensor and my afr's were less jumpy on the gauge. Are you using a gauge on the dash for AFR or getting the signal from the microtech? i used the megasquirt ecu so its going to be different and i know nothing about microtech. but afr is adjusted in the VE table, smaller number is less fuel ie leaner mixture, larger is richer. what size injectors are you using? are they new? or rebuilt? or tested even? your issues could all be in the tune and eventually it might be beneficial to find a dyno and a tuner that knows rotaries and get a pro to tune on it. a base map is exactly what it says base just enough to fire the engine up and start tuning from there.

 

Well I think my main issue is fuel. My fuel pressure regulator is saying only 20 lbs. I am going to track down my fuel line and see if the filter is just clogged.

Im reading afr off my wideband innovate o2 sensor with gauge setup. The micro afr reading is diff when running but i trust the gauge than the micro... haha

My injectors were cleaned and fixed my injector wizard locally over here in WA. He has his whole workshop in his backyard :p He said my flow charts were good and even before they would of worked. So i know they are improved.

Well my base map is messed with so now i used the base map listed in the micro foum, don't know if thats right.

the only tuner around here is in gig harbor about 4 hours or so from me. Since the car doesn't drive, I have to tow, big dollars there. And the tuner will msot likely charge an arm and a leg which I don't have at this point :p.

I will trouble shoot it some more and see what I can come up with

 

what signal wire from the innovate did you wire to the ECU? the yellow wire is a narrow band signal so if thats the one going to the ecu might make things a lil screwy.

 

OKAY... I figured out what was going on with the engine. I traced the no fuel pressure back to the tank. Thought the fuel filter was clogged. Nope. Thought the fuel pump wasnt working, quirted fine, thought the tank was cligged, nope. The tank had nothing in it. Literally, NO GAS! hahahahaha. I am utterly stupid. I changed my microtech maps and contemplated sending it back to AUS for nothing. :p SO I went and premixed 4 gallons at my 76 gas station, siphoned it in. Turned it over, while my dad set the fuel pressure regulator to 43lbs and she runs perfectly again even with the only 13b tII map available on the net for microtech! So, now I get to check my values and see everything that is running when the engine is warm. Will try to get a vid today.

My next two projects are to convert my transmission connector from manual to electronic to work my new speedo. And I need a fuel gauge obviously, and a bov. I am thinknig the greddy bov type-rs. I want to plumb it back into the exhaust and not fart into the air obnoxiously.

 

I am glad to hear it was just that... I did something similar... twice. The gas gauge was reading 3/8 the second time.

 

Okay, here is the car started! This vid was taken and uploaded before I tuned it. Which was earlier today. I tuned the car to run smooth up and down the street under load. Will take another vid of it running better. But for now, enjoy

Okay, so I attempted to just get the car rolling down my neighborhood for once. The car is bumpy due to the urethane. But, the microtech needs to be tuned more due to some rev studders through some rpm. But the car won't rev past 3.5k which I kind of thought might happen. I was on the phone with gary (microtech tuner in WA) and he said the microtech is setup with a fuel map to 4k about and then a second map must be applied to make the car go above 4k. I drove my car to 3.5k and it won't go any higher even floored.

How do I add the second map to allow the higher rpms to come in? I would rather do it myself that pay big dollars for a tuner if I can get it done at home you know :p

thanks

Will add a vid once it is actually running. And it WILL be a running video of its first actual drive! Stay tuned in. Once I get the 2nd map applied I will put a vid up so help me out ;p

 

Just so you know, you HAVE to put on an ic before you try boosting it. if you dont you will have to rebuild the engine again, this is not a maybe situation, it will happen,
rotarys are wery different from piston engines, the combustion is by design alot hotter, even with an ic its wery hot, add uncooled boost to that equation and the internal engine temps will get to the point where the fuelmixture will preignite, this will "ping" and you will have 1 ore more failed apexseals/sideseals and in bad cases imploded rotors.
the only way you can get away with no IC is if you add a water/meth injection kit.

im not saying this to annoy you in any waym i just HATE to se a sexy *** rotary build fail for stupid reasons
So pleeeeease, for the rotary gods sake, cool you intake temps!!
(or meth the ******, might get some cool blue flames to xD)

 

Thanks for your concern Mr.veilslidewankel. Yeah I have bee nlookinig at intercoolers. There are some very affordable ebay specials that I might be able to fit. Nothing large large but atleast one would be installed then. I'm waiting on my credit card fraud to be fixed (long story short, someone donated all of my savings to red cross in Japan and now I have to get it all back somehow)... Once fixed, I will look into the intercooler okay?

Also, I posted under the microtech forum a couple times about bringing the ngine past 4k. My local tuner said he could put a 2nd map in to go past 4k. But many of the ppl on the site say he is full of sh*t, can you guys help me find the setting that allowds the engine to go past 4k? yes I have searched and looked in the manual all over again today... haha

 

I am thinking you might also have a timing problem. From what you said eariler you just lined up the crank angle sensor and put it in without finding top dead center first. Maybe you did find tdc and I missed it... https://www.rx7club.com/showthread.p...&highlight=tdc

 

I know I haven't posted in a while. A few things have changed and I couldn't do much after having my microtech have issues again. So I called AUS and they sent me another dongle with a cosmo map installed this time! To put it on my lt10s I needed a computer with a 9pin port... So I went out and bought a cheap 109 dollar comp off the net. I just had to set it up. I received it about 2 days ago. I have an old windows 98 im trying to put in it because xp and 7 gave me **** with the program last time. I can't get my 98 to install on it, keeps saying setup files not found etc. So now that is my predicament... In the mean time, while the comp was in the mail, I worked on the car some more. I took the forum's advice and bought an intercooler as soon as I found one with the right setup for me to mount up to. I remounted my oil cooler on the water pipes down below and welded some tabs on there that should hold someone standing ontop of it :p Now the intercooler should fit up above and I will cut my new fiberglass deck lid to allow for the cooler to poke out when the hood is down. So, the hood will look like it has a grill in it but really it just has a hole for the cooler. That's what I wil lbe going for anyway With the inlets and outlets afcing down on the IC i can pipe them righ to my manifold. I am going to make a new merged connector from the throttle body to the IC for a nice vertical pipe job. Before the engine crapped out, I was able to drive the car. It was quite a bumpy ride to say the least. I realised the torsion select-a-drop mod was doing nothing. So I had to take out the rods and preload the arms for suspension. The rear end was slamming the ground on bumps. SO I modified my rear bilsteins into coilovers. I am using carrera springs at 200 lbs. Then those felt too seft and I just bought 250 lb springs. Much better now and this way I am fully adjustable and that torsion bar in the rear is now gone! Next post will have pics!

PS: Anyone have an old copy of windows 98 or 2000 that I can use for my "microtech use only" computer???

 

This is the remounted oil cooler:



This is the new 21 inch Intercooler:



This is the 250 lb carrera spring waiting to be installed:



And the next two pics are the coil over bilsteins installed on the car:

 

Nice job!

 

Okay I got my new computer working with xp.. PLugged the dongle and ecu up and it connected! I asked the microtech guys if preloaded dongle maps are named and got no response. So I went ahead and loaded memcal1 and it was a success! PHEW! The car's new map starts and runs a little rich but it runs better than it ever did. The idle is at 1k when it use to be at 2k. I had a little trouble starting it becasue the rotor housing were extremely flooded and that fouled my plugs, then no auto store had bur9eq or the 7eqs except action auto parts. Gotta love that store :p It's pretty bad when the employees there know my whole family and every car we have So the new plugs fired her right up. Now to install new carrera 250 lb springs, drive it and see how suspension works. then on to forming the deck lid around my new IC that is yet to be installed.

 

What trans axle did you wind up running on this setup?

 

This is such a sweet project.

 

I must agree as well, this is a sweet project! K U D O S to you!

 

Sorry for not updating my thread in such a long time. I had some major issues with my account on here. I use the facebook login as my account login and it ALWAYS said error. Now it works all of a sudden. How do I change my account to a normal one with a password etc?

Anyways, lots of updating to be said on here! My rotary is about to live again. It was down for a while. My twisty turbo pipe is laying on my garage floor in pieces :p. Guess why? Intercooler is mounted baby! It is huge and now looks kind of awkward on the engine. Made a new intake pipe to mount from throttle body to intercooler with a mounting flange for my new greddy type rz bov. Actually, I need to mount my map sensor in and then I will be starting it tomorrow after its long hibernation. Mechanical speedo now converted to electronic through a homemade adaptor. I installed coilovers in the front. That was a huge process. Had to weld a new mount for the top shock mount to fit right. the 200 lb springs were too hard still for the front. I bought 125lb or 130 can't remember and the bug still slams the ground in the front haha. So more tuning needs to be done there for a softer street ride. :p

Hopefully if I can log in or change my account from facebook to normal tomorrow and I will upload pics and maybe take a vid of its first start with new parts tomorrow! For my followers, the thread should never have paused but I blame the fb login!

 

BTW, If I can't log back on on this account tomorrow then I will try to make a newreal account on rx7club with a different username. Just letting you guys know

 

looks like this project is coming right along. glad things seem to be working out for ya. PM a mod on ur login issues. maybe one can help u out without having to start over with a new userID.

 

looks great

 

Here is a running vid of the latest intercooler and bov installation.

http://www.youtube.com/watch?v=nb-JdZLXC1w

You can't really hear it in the vid, but when I hit boost at 10lbs or so a weird noise occurs for a second. My dad says it sounds like the same noise a piston knock makes. If anyone know what it could be let me know. Ill get another vid of just the engine running and try to get the noise to happen. And ill get pics to show you the massiveness of the cooler ontop haha.
