Thread: How do I not have KR in this scan? I know, odd question.

No PE Batman from lightfoot3b -- Scan Depot dot net

Notice the air to fuel ratio and injector pulse width with my mods and wot.

If I have PE enabled I run slightly faster, with IPW of 21 and about 15* of timing. I don't get how 50% more fuel only adds a couple ponies.

you were going WOT? how is your A/F ratio 14.7 still? what does the scan look like with PE enabled? what pulley are you running?

of course 99% throttle. I set PE enable @ 100% meaning i need 100.01% throttle to see PE. I have my smallest pulley on, 3.15". 8psi at redline.

Update:
with pe set at 14.0:1 I could not add anymore timing then with no PE enabled.
with pe set at 13.5:1 I could only add about 1 more degree of timing. (ipw @16 during this run)

what injectors are you running? an IPW of 16 seems way low for that pulley.

i dont know how to tune..so maybe im just taking shots in the dark here. im not sure what PE does.

Sorry, I was being a little sarcastic with the title.

I'm surprised no one else who does tune was surprised 6* of timing can be pulled, and with it 50% of the extra fuel.

Yes that IPW is very low for wot and my mods. PE adds fuel (power enrichment) when you are over the pe % of throttle (usually around 35%). I guess this would be amazing for road racing and getting way better mileage while racing... but other then that just sorta fun to see the results.

I'm down 10-20 horses I would guess when doing this. Still a lot more power per unit of fuel though! Kinda makes me wonder what a smaller pulley would do.
