I'm having a low speed stalling issue, which I think is due to the lack of a VSS. I'm sure someone (Mike maybe?) posted a cheap wheel speed sensor that works, but I can't find the post. So, suggestions for a speed senor that will work with the GM ECU?
You don't need a vss with the gmpp crate engine ecu
The tune in mine flat out sucked donkey balls. Really bad a/f, stalling, it was pulling something like 16* of timing, no rev limitter, etc....; works out of the box w/ no tuning my ass.
you still need to do a dyno tune - GMs tunes are notorious for being a sack of crap; I figured how bad could they be, until my tuner showed me my base file.

I didn't have that experience, mine was dead on accurate for the engine dyno... In the car, not so much, it's running rich and I can tell by the good ole 'sniff' test. Which will require a chassis tune.
