427 sbc with Sniper EFi headaches
I am relatively new here...
Car is a Camaro 1969 conv. Auto RHD (I am in Australia).
With the original 350 SBC (300hp) it was smooth but slow
The new SBC Dart SHP 427/AFR 210 heads/ CompCams XR294HR/ Sniper EFI, and all the rest of the good stuff.
On the Dyno it was great around 550Hp and 580lb all under 5700rpm, perfect for the street. Between the engine
Dyno and completing the installations, my engine builder and I had a "disagreement" about the responsibility of leaks...
Anyway, to my problem...
After a few hundred miles I decided to put it on the chassis Dyno, well that went bad besides only hitting around 350rwhp,
with only I pull I smoked out the whole workshop...
My tune is no good...
Here are my stats:
IDLE jumps between 800-950, set to 900rpm
Is there a way to reset the the Sniper so it re-starts learning from scratch?
and are my starting points (AFR and Ing) ok?
