Okay guys bare with me, I know there's information covering but something isn't working for me.
I swapped to GT35R
with a rebuild/large street port from pineapple racing
I have stock primary injectors and 1680cc secondary
Aeromotive fuel regulator set to 40psi at idle
Running a base map, re initialized the pfc
I'm running rough idle's good, but when under load at around 20mph it starts to stagger, as far as I can tell from my wideband I'm staying rich, so I'm thinking it might be flooding. I'm trying to figure out a map that I can run the car for the break in on but haven't been able to figure something that is drivable.

Thanks for any help,
Steven

Did you properly setup the secondary injectors values on the injector setup screen?

Devlian

I'll admit I'm in a little over my head, on the setting tab 5, I had the value Q secondary set to 1600, so I'll change that to 1680 to match the injectors right?

Devlian

I uploaded a zip file containing my current map, and a log that ran from idle while warming up, to driving around my neighborhood, until it hit max lines and stopped logging. If anyone feels like reviewing them and offering any advice I'd greatly appreciate it.

You don't have wideband data recorded in this log, so that makes it harder to figure out what's going on.



Basically there are multiple instances like the image above. Basically, you are cruising along with mostly steady throttle position and vehicle speed, and then the knock sensor goes crazy with your manifold pressure getting noisy.

I'm certainly not convinced that you've got actual harmful knock occurring (given the low load condition), but something's not right. It seems like a misfire. It's certainly possible that you are lean in those areas. It's hard to tell from just eyeballing an AFR gauge. You did make some small tweaks to the fuel in that area. It's probably not enough to make a difference but I can't say without data.

Also, your timing is jacked up. It looks like you took the default leading timing and retarded it a lot in an attempt to make the tune safer/more conservative. You forgot about the trailing side though, so you have erratic split. IMO your leading is too retarded at high rpm. You'll just get high exhaust temperatures.

Can you swap in the default map real quick? You don't need to reset the PFC. Just swap it in using FC edit. Next data you upload should have a wideband input. You also need to check all the basic mechanical things like spark plugs and air leaks.

Devlian

I'll have to do it tomorrow as its getting late, but I can do that. To include wideband in the monitor log, I click the box under "datalogit" in the bottom right corner of the monitor screen that corisponds with AUX a/d right? Thank you for your help so far.

The IGL is one of the worst I haver ever seen and reminds me of timing limited by a distributor ignition system. That along with IGT proves to me that you do not know what you are doing.

Stop, collect $500, go to a real RX7 tuner.

Or contact "arghx" about joining the PFC tuning group, read all the tuning notes, learn, then try again with some knowledge.

Devlian

Like I said, I know I'm in over my head, I didn't modify the IGL or the IGT so the "stock" map I have been using apparently isn't stock, I swapped maps to what is hopefully a true stock map as you told me to, and my idle became rather rough, it smoothed out after a bit, but once the car hit operating temperature it died. I'm not trying to get the car tuned like a pro would right now, my goal is to make it drivable so I can break in the newly rebuilt engine and go to a real tuner.
this is the "stock" map I have, hopefully unmodified and a log from it warming up. But I don't think my wideband aem uego pn# 30-4100 is being logged correctly so I'm going to have to double check the wiring on that, red power, black ground, white wire to an1, an2 grounded, and ignore blue wire right?

okay so looking at the way my wide band is wired in, its wired into the fc commander, should I cut the white wire from there and wire that directly to an1 on the datalogit?

Which wideband do you have? It should have a 0-5v output wire. Run this into the AN1 connector on the Datalogit.

In the FC Edit software go to the Setup drop down menu- Auxiliary. The first block is AN1, and has 0v= and 5v=. Use the manual that came with your wideband to input these figures. Create a Watch or go to Map Watch/AN1 and see if it's reading correctly compared to your wideband.

Devlian

the white wire is listed as 0-5v output, and the blue wire is serial output, blue wire isn't connected to anything, and the white wire is spliced into the power fc harness,

Wideband are only wired to their own meters or to a DATALOGIT. Never to a Commander.
Who did all of this crap? Hope something did not get fried.

(1) Re-initialize the PFC using the Commander.
(2) Change the secondary injector setup to be for 1680s instead of the 850s.
(3) Since I do not think you are running an airpump, switch off the O2 FB.
(4) Check and set the TPS voltages to stock values.

Devlian

Thank you guys for all of the input and advice. I re-initialized the PFC. I wasn't 100% sure about the setting for the TPS so I need to some more reading to verify they are set to stock values. as best as I could tell eyeballing the gauge and eye balling fc edit while driving it is reading with in .3 of what the gauge is reading. This is a log of the same driving conditions going around my neighborhood.
