Your feeble attempts to belittle anyone else's experience or knowledge shows quite clearly that I'd never touch your car - simply because you're showing yourself to be as nut-swinging and close minded as the MKIV crew. Maybe you should just head over there, as it's more your style.
Dude - you consistantly try to argue with me about everything, and you dont know WTF you are talking about.
I dont claim to be the "allmighty all-knowing" engine guru who is never wrong, but when you were just a NOOB figuring out where your intake tube goes about a year ago - http://www.supramania.com/forums/showthread.php?t=10833 - I had already owned my 7M for 8 years and heavily modified it and ran low-12 second passes... I know that isnt the best time but it was on a motor that I BUILT MYSELF. The only reason my motor failed was because of the THRUST BEARING which was killed by my RPS clutch and possibly the soft clevite bearing had something to do with it..... A lot of people have had this happen with the RPS Max Pressure plate on all different types of cars.
I know how the 7M is built and I know how the 2J is built because I have TAKEN BOTH ENGINES APART AND LOOKED AT THEM instead of conducting virtual bullshit and hearsay to build a foundation for my answers.

Yeah, I wish.
How about when you are done with your ghetto-ass setup we take a little run at the track?
No go back and read everything you posted and see how STUPID you look and then STFU
X-man said:I tried using the the ITC to change timing under boost and never really saw much in the way of increases. I played around with the fuel psi and the afc alot to keep my corrections to a minimum. At 31 psi of boost I was at +1% correction to no higher than +8% in the upper rpm range. I did not want the ecu doing more with timing than it was supposed to and I figured the best way to do so was to keep corrections to a minimum.
The a/f's on the dyno were pushed to 12.0 to 12.3 but on the street at 19 psi they were kept at 11.5 to 11.7 and at 31 psi I kept them at 11.2.

Thats one reason I went to the AEM - so I could control the timing.
Safe is good - how did you figure out the lower AFR's for higher boost pressures? Was it just a seat-of-the-pants thing or were you using some type of formula, calc etc?
Ive been looking for some type of "detonation" or pre-ignition calc to approximate my boost and fuel level limits considering air temp etc..... Do you know of one?
