I picked up an offbrand speeduino ecu from ebay (trashy right) and got it running decently and starts okay ish but that's not why were here. 1994 should be original motor haven't checked the pan yet but 169,1XX miles.
For the life of me I cannot get my idle to come down normally when warm and not only but it idles low when cold starting. Already tried reversing closed loop PWM on the idle control and adjusting things based on coolant temp as per youtube videos.
For diagnostic I unhooked the ISCV and the car stalled indicating a low idle, got that idling at 800 ish with the idle screw with it disconnected, stock ecu acts no differently.
Attached is a datalog and the current tune for reference, I can send the whole config if you need it this thing uses like custom firmware and stuff as well.
sensors are calibrated correctly to my knowlege, using stock MAF for intake temps even though it's pre turbo intake (gm sensor coming in mail).
Any help is appreciated
