1990 Eclipse GSX with mods on my profile.Car was running great when I shut it off, I came back out a few minutes later to it failing to start. After some time and many attempts, it runs but it won't stay running. It will run OK for about 5 seconds if I get it to a point where I can hold the...

I do not have anyone with a map sensor I can try out. Looks like I'll have to order a new one. Any recommendations for one or should I get another Omni 4 bar since that was working fine until now?

Got it, thanks! Here is the log.

I cannot, for the life of me, find out where to attach a log file here. Could this be because I am a probationary member?

Hello! I am stumped trying to diagnose a problem on my 90 GSX. I installed a new trans and put about 25 miles on the car since, it was running great. I was about to capture a driving log to send to my tuner (as my tune wasn't 100% finished when I blew my last trans) when I shut the car off and...

Found the spot where it idles good around 900rpm when warmed up. Still having an issue holding a steady RPM if I'm less than 50% throttle or so (shown in log). My AFR sensor/gauge is reading 7.5 again. There may be a loose wire somewhere... It seems to work on and off.

Car starts hard and idles very high and rough. I see now that the TPS idle voltage is not the same for different throttle bodies...

I am running an S90 74mm throttle body. Is there something different I need to do? The screw that changes the voltage is on the top and the side closest to the throttle cable. I adjusted it until I was seeing .63v closed. There only seems to be one more adjustment screw, and it is on the bottom...

What should my TPS Offset and TPS Scale be when I begin the throttle body adjustment process? Or should I completely disable TPS adjustments prior to adjusting the tb? I read up on how to do it, and it seems fairly simple step-by-step.

I unlocked all of them when I wired my wideband to the EGR temp pin. I assumed that if the egr temp was locked, it wouldn't read wideband correctly. Not sure, but I'm just going to leave them all unlocked unless I come across an issue that I think is causing it. Thanks!

Thank you both! I have changed injector deadtime from 450 to 330, zeroed out my fuel sliders, copied over the 2g timing map which is a little more conservative, and changed wideband to undefined in the ECU Inputs tab. This shouldn't change anything if narrowband simulation is disabled, should...

Perfect. Then I will take it out for a mild drive and return with a log.

No worries, just double-checking. I'll reduce global injector deadtime by 50, and adjust TPS this afternoon. Anything else that jumps out to you? Thanks!!

Are you sure I need to enable narrowband simulation? I still have a Front O2 sensor.

Thank you for the link. I didn't have enough time last night to get to my TPS. Hopefully I can get that done this afternoon. I have a surging issue under partial throttle when revving. It is impossible to hold the car at any RPM higher than idle for more than about .5 seconds. Maybe this is...

Thank you everyone for the help. My car is a lot less broken than at the beginning of the day, and I am learning a lot! I wired the wideband into the EGR temp pin and changed the settings accordingly in ECMLink. Also, I think my 4 bar MAP is wired into the Baro pressure pin (not 100% sure), so I...

I changed some settings and tried to "fix" my TPS. Not sure if its right. 5.0V at full throttle and around .35v at idle. Anyway, here is a log of idling (not completely cold, but not warmed up) and some short revs. Thank you guys for the fast responses and being so helpful!

Rear O2 is missing from Pin Assignments in ECMLink... This is where my wideband is installed. I also have an O2 sensor installed in the Front O2 location. Does that mean that I can disable narrowband simulation?

1g, Speed density, stick.

How rich does it have to be? Its running 11-14 AFR

Got it! Here it is. I'll gladly pay for your gas money if you want to make a trip up here and help me out, haha :)

Hello, all! I am very new to the DSM world. Bought this car from a guy that was moving out of state. Finished up a few things mechanically and now it is in desperate need of a tune. I've spent a lot of time searching on forums and reading wikis/guides. I know this tune is not optimal...
