Hey all,
Just got my PoS up and running with a turbonetics 7668 and MSPNP2. I used the base file from DIYAutoTune to get it fired and adjusted the fuel injector size. Tonight I finally got the Boost controller and wideband wired up and running (wideband verified at least). I'm ready to start learning to tune and get started in the right direction. I got a datalog tonight so hoping I can get some insight on the startup and idle.
I'll start with the basics of the car:
89 Foxbody
MSPNP2
Unknown miles 302 block (possibly 70's era per the stamps)
D8 heads w/dual valve springs
E303 Cam
Turbonetics 7668 Journal Bearing Turbo
42 lb injectors
Pro Comp Victor Jr/Edelbrock Upper intake
AMP EFI boost controller on Turbonetics WG & 9lb spring
Zeitronix ZT-2 wideband
Wiring harness modified to delete all emissions/AC parts
Colorado based car (~6,000 ft ASL)
I captured a cold-ish start datalog which is attached. At idle it is super rich, and while the wideband eventually starts reading, it goes through a period where it reads 19+, and then comes down to a normal reading. I dinked around with the accel enrichment and VE1 tables per the documentation to see if it affected the idle AFR but no go. Still lots of fuel at idle. What am I missing here?
Thanks in advance!
Bob
