Hey yall,
I am having a weird issue. First, I have a CEL light on. I am using a turbo chip from sssquid with fuel and time map. (yes i know ms2 is better , but that is out of budget) When I go WOT, the car cuts off around 4,500-5,500 Rpm. The cut off feels like a red line. The redline is set to 7k and if I pull very slowly, I can hit 7k. As soon as the boost gauge hits ~5psi the redline cut off thing kicks in. I have a wideband o2 (lc-2 wired narrowband into black wire o2 harness) The afrs jump to around 15 when the cut happens. On idle afrs are around 15.5. Underload (before boost) they are at 10-10.5. Under boost it is around 12 (before the cut). I tried a stomp test but nothing happend. Any ideas?
1987 325is 2.8l turbo with a 380 ecu
Thanks
