Get a vafc and make use of those mods! I saw one ebay yesterday for a decent price. hold on...

false.

on my old setup, FIPK, Berk high flow cat, and invida v1 ( 63mm ) and tuned perfectly with e-manage ultimate, i still hit over 14 in some spots after installing my ricks header after that. re-tuned and everything was great.

just cause you've never seen it...doesn't mean it's the truth.

 

There may be a miscommunication here. When I said that I haven't ever seen an AP1 with I/H/E run in the 14's, I was talking about untuned AP1's (the topic of this thread).

Your comment seems to be about a tuned S2000 that then went lean because of a header. If so, then I agree. A perfectly tuned engine is going to run lean and need a retune after the addition of any good breathing mod. Of course, that's off topic with this thread.

 

gotcha. i see your point then

 

'00 and '01 ran fairly rich. '02 and '03 are comparable if not on par with AP2.

 

[QUOTE=Jspd,Jan 27 2010, 03:43 PM] '00 and '01 ran fairly rich.

 

Let me clarify that I am speaking of non-DBW ecu or pre '06. It is well known that '06 and up will not see much increase in peak hp from piggy back units, however K-pro and a few others have increased and smoothed out mid range power delivery with reflashed ecu swaps.

 

Ah, well, I think that narrows your statement down to just 2 out of 6 years that AP2's were produced.

I've been tuning my '08 AP2 with a FlashPro, and have definitely found power here and there, but nothing like I did on my '02 AP1

 

This is quite an informative thread.

Can someone tell me how my air/fuel ratio looks?



My only mods are:
snorkel
gutted airbox with k&n drop in filter
test pipe.

 

Your AFR looks similar to my AFR curve in my '02 before I tuned it. I suspect you would be able to achieve similar power gains as I did using a VAFC or NEO.
