I'm new to the site. I finally got my 87 T2 up and running... But not so well.
I got rid of the extra garbage on the intake manifold. So I finally got it idling decently with my wolf3d. But I got the car going, and i try to drive it and i'm almost positive it's blowing massive raw fuel out the rear end. I have good spark. but it's drowning it out under basically any load. I checked the plusg and they are black. So I'm gonna pick some new ones up (fouling, obviously). and as i drove it to my parents house last night, i saw basically flames out of the tail pipe as i was STRUGGLIUNG going up a hill, and running rough as hell. But the a/f on the wolf was saying like 13.9-15.0:1 So I have no idea. Adn the second I hit 10psi it freaks out rich/lean i'm not sure. I need a a/f gauge.

I got the 3mm apex seals. upgraded injectors "RC" i believe? stock tmic, good cooling system. 3 inch exhaust all teh way back. I'm sure it's teh stock turbo... Maybe slightly bigger (I bought it all messed up from some guy).

BAsically I need a ignition map/fuel map to get it going. the one that was on there was super rich and it wouldn't run worth ****. Please help someone? WHatever specs you need I can supply. Just ask. I appreciate it.

 

what injectors are you running?flow i mean.

post your current map pls.

i would do a search... there a quite alot of maps on this forum.

the flames out of the exhaust make me think that the ign is way too retarded.

 

I'd like to say that they are either 650cc or 750cc. The guy that originally owned the car went to the military, and his brother sold the car for him. But they are RC fuel injectors.

Also, i'm sure that the ignition could be super retarded. What is the usual timing you want on the Rx7? Usually when i'd time a stock one, it'd just have the leading/trailing marks. Also, the TPS makes the load 107% almost instantly, but there is tons of throttle left... Secondary inlets? Which kills me!

Thanks for the input. I'm at my work computer, so I don't have a ignition/fuel map for you. But really, any decent fuel/ignition map would be a good start.

 

well, i can send you this.... but you still need to calibrate TPS, u need exact fuel flow injector figures... approximations wont work.

just use the fuel (+staging)and ignition tables.....DONT tranfer aall the map. its from my fd, and is not like the fc. as it is it wont work .this was with 550/850

 

Alright, I got it up and idling good. And it cruises fine too. But once i put my foot into it and get some boost (5-15psi) you can feel it struggle and choke. the injectors are 550cc 1000cc. Also, I tried to use the hand held while running to put a percentage on staged injectors and it wouldn't go past 0 percent. So i checked it out on the computer. and it gave me RPM and LOAD options.. I can't tell if i'm not getting enough fuel or the right timing. my a/f says 13.5 right before boost (crusing) then goes into the 14's. I have yet to see it go below 13 regardless. Anyway, should i still steal your fuel map? i'll post my plugin and please tell me what the deal is.... quick mods.

3mm seals,
stock tmic,
dual crane coils; jacob's ignition computer.
greddy BOV,
wolf 3d v4
3" all the way back
100% aluminum koyo rad
electric fan mod
RC secondary 1000cc

 

also, woul dbe GREATLY appreciated (i've seen a lot of your work with plugins, and it looks good... from what i can tell, heh), if you could modify it and repost it for my application.
Thanks

 

Ok I know whats wrong with your map you are double firing your staged injectors. Go to Configuration the engine then Injector sequencing then Injector staged pulse skip and set it to 1... Your engine will be PIG rich too and you need to reduce your pulse width below 6 ms becasue at high rpm the injectors will not be able to fire when they are told to and the Wolf gets tied in knots...

I have changed the Injector staged pulse skip for you but you need to bring the staging in earlier. I have all my staging in by 57% and I start it at 28% ....at 57% I use between 4.5 and 4.90 ms and I have 550/1000 with a hybrid S4/TO4 on a 13BT TII. I do have a map on my laptop but not here.

Hi,

sorry for the late response.
I agree with michael.... I arrainged your staging... it will be rich....and i put in a new fuel map.....

this is after you set michaels recommendations... ie Conf/Engine/Inj Seq/Staged pulseskip =1

turn off ecu and reload....

hope this works for you....

awesome. ill go throw these in tonight. although i did change my fuel map kinda like signofinfinity but at high end it was struggling. So i changed the ignition curve to be 40/45 with low load(what you typically have), and made it end about 18btdc (at 107%) and it stopped the struggling; well it still does need tuning at above 6k rpm, but it works a hole hell of a lot better. is that because of the double firing? yea that kinda makes sense, considering i've been getting terrible gas mileage, haha.

Thanks for the help! ill post soon and let ya know how it works.

 

Way too much timing!!!! I would use 15 deg max at 15 psi and I run about 13 @ 15psi and go down to 10 at 107% ( 23psi) in the low load areas ie below boost I go to 25 Max on very light cruise.

With the double firing what happens is that say you engine takes 10 ms for one revolution well the primary injectors fire every 20 ms 2 rotations so they work great but if the staged skip is set at 0 ie skip no pulses then if your pulse width was 10 ms it wouldn't be ready to fire the injectors again. What I suspect the Wolf does is that it misses the next pulse making it lean for 1 revoution. Double firing is usually used if you have small injectors. If you use double firing you staging can't go beyond 50% with large pulse widths.. Hey George maybe thats whats happening with your engine ???? I didn't think of that last night!!!!!

P.s. Jerek10 do you have a standard or modified Crank Angle Sensor like the old Version 3 Wolfs required????? I will get you my maps but you will need to only get the map data from it. Keep your configuration data....and don't forget to save your map you have now first OK.

 

18degs???? no way!!! bring it down! dont boost on 18 deg!!!!it a sure was to blow a seal.... i did!!!


I am running 10 degrees.... tops i ever ran was 14 deg at 1 bar....

george

 

michael.... i am considering to go on the stage pulse skip.......

i think thats why i get shitty milage too!!!

 

oh boy... the scary thing is. this morning when i fired her up.... when it was super cold. i think it was burning something other than fuel... maybe... not oil... maybe coolant... but after it warmed up it was good... but ill plug that in soon.

 

oh and i believe it's just a stock CAS. how can you tell if it's modified?
htanks,
Chase.

 

okay so this is the latest scoop.

I put in your fuel/ignition map. and changed the pulse skip for the staged injection.
when i barely lean into the gas it'll go. but if i put any load i'm not sure if it just c uts ignition completely, or fuel. but it just acts as if i just turned the key off. it idles good. and starts up fine, just under a load. ill post the plugin i just put on the wolf3d

 

Well.. ignition was off... i gave you my table... forget running 18 deg.
your staging was still out.... at 87-107 you were running 89%
so i upped the staging... see how this works out... but its a bit hard to do all through here the closest i can understand and figure your car might need....

good luck... this should get you started.... keep us posted.

George

 

As promised here is my own 550/1000 map it does work(for me) but is NOT GOING TO WORK directly with your setup. If you go into admin mode {see dealer tech at the Wolf web site} and copy only the fuel/ spark/staging into your existing configuration. BTW I have never done this myself. Or you could do it my way very slowly one at a time.. Also follow the calibration proceedure for your TPS...My guess is that you are running a standard TPS which sucks big time. I have installed a VDO TPS on the back of the throttle body and remove the plug from the factory one this was the single best thing I ever done!!!

P.S please feel free to pick it apart anyone else who has ideas. It is very rich above 50% richer than 10.1 AFR at 6 psi
