So just before Christmas I got my turbo install all done, and got the car up and running. I'm having a lot of trouble with the idle on the car (seemingly only when its warm?). It hunts, fluctuates like crazy, and dies if I take my foot of the accelerator. I'm new to MegaSquirt, and new to tuning, and I can't figure out if it is just settings or what.
Here is a post in the build thread with Pics and Video: DS1 has a horrible Build Thread.
I am going up to the shop right now to work on the car and diagnose it more. I also bought an automatic throttle body to do the 1.6 TPS to VTPS conversion, as I have read that could be a big part of the issue (at least the stalling).
The car is a '92 1.6, with Greddy-based turbo setup that now includes an intercooler, MAF delete using GM IAT, BOV, and the DIY Autotune EBC solenoid. The ECU is a Brain-built MS3X. Injectors are RX7 460cc's. Wideband is Innovate MTX-L.
Any ideas what this could be? I will be checking for vacuum leaks today. I will also record the setting file and post it later so you can see the idle settings. Right now they are whatever Brain sets (or doesn't set) them to. Thanks!
