Thanks for your time in advance,
I'd like someone with someone with more experience than me (none..), to look over my tune if possible. I know there are some threads with similar topics but I'm having trouble using those to verify my maps.
This ecu was sold to me second hand, previous owner claimed that there's a startup tune for the m20 on it, this is what was on it when I first connected. I was planning on using DIY Auto Tune to work out kinks (is it actually any good?)
Okay lets get into specs:
Car: 1990 525i (yes its not an E30 don't kill me)
Engine: M20B25, sort of fresh head, ARP studs, 440cc injectors, OEM style head gasket, perhaps some blowby (leaking oil from intake)
Turbo:
Turbine Trim: 74.2
Turbine A/R: 0.63
Turbine Inducer: 64.8mm
Turbine Exducer: 55.8mm
Turbine exhaust outlet : 79mm
Turbine exhaust inlet: 44.7mm（length）/85.8mm（width）
Compressor Side:
Compressor Trim: 48.1
Compressor A/R: 0.5
Compressor Inducer: 52.7mm
Compressor Exducer: 76mm
Compressor outlet:78 mm
Compressor inlet:51.5 mm
Sorry that was a lot, don't know if its necessary but its here.
Target: For now I'm looking to go as high as possible while being reliable in the sense that it wont just blow my engine after two months, this car is a street car that I use daily for the most part. I was thinking 6-8psi.
Please let me know if there is anything obviously wrong, any general tips are welcome, post your map if it fits the specs closely enough. If you post your maps make sure to provide all the necessary information on the engine and setup.
If anything else is needed or wanted for a more informed response let me know and I'll add it up top.
