sounds like its suffocating. right after start up it enables the idle control valve to bring the idle up to ~1000 after 30s it shuts the idle valve and relies on the air regulator to raise the idle until it warms up and then the air regulator will close. so either the air regulator is stuck closed o...

how would you modify a stock image for e85. just adjust up the fuel mixtures or can you change timing too?

i attached the latest log. ill try the repair maps. i'm guessing it needs to be connected to consult for that will work.

so fuel pump is fine. now im starting to think my ecu is faulty. previous files that ran fine are not working as intended now. and the timing keeps having blips. it will drop out for a second and return or during warmup during acceleration it will just drop down 20 or so degrees have no power until ...

timing was fine with the light. i think my fuel pump is on its way out.

im going to try and get a timing light on it and check the indexing on the distributor. im also getting an rich smell while driving.

ill give that a shot. i was playing with it yesterday and played around with fuel and timing. fuel seemed to change nothing with the bucking but when i changed the after start timing advance from 60-110 and set it to 10deg it seems to have made it much much better. but it seems something is still no...

i was planning on putting a turbo in the car at some point. i wonder if there was some confusion when i ordered nistune. the bucking pretty much happens anytime i accelerate semi quickly. if i drive like i have an egg on the throttle its not as noticeable. today i changed the spark plug wires and ig...

none of that made a difference. whats weird is sometimes its better and sometimes it worse. sometimes just turning off the car and waiting a bit and starting it back up seems to make it work. yet still not quite right.

could it be a fuel delivery issue?

i do have a manual transmission non turbo. so do i need the speed and auto trans on?

Hello, im having an issue that i cant seem to solve. im getting a surging/missing when im under load. mostly between the 1000 to 3000 rpm range. its an 86 z31 na it has an 86 z31 turbo auto base image on it and im not sure if that is causing an issue or if my ecu is being wonky. during warmup on som...
