btw..i hardly call 11.2 lean. Hell i hope you have some injector room left with that 10.2 afr. I know i'm already up to %93 duty cycle running 11.3 so you're running static right now. Any more revs and you're just out of fuel. Could lead to a blown engine if he revs any higher. Guess you guys never realize what's actually going on in your own cars. You just look at a dyno graph and see the max numbers and go, looks good to me. I'd hate to see how much more fuel it needs if this guy goes with cams. Anyone with a dyno and half a brain can put up a number. I bet you didn't even work on your own car. As for the comment about adding timing at a given load or point. You're just as blind with the xede as it doesn't show ACTUAL TIMING NUMBNUT! You're just guessing what the ecu WOULD run and then do your timing tweaks there. Got any other comparisons you wanna throw at me while we're at it?

Such an original insult lol. Anytime now someone's going to throw out their e-cacks to make them feel better about themselves. A little insecure mr alex?

Granted it didn't hit 20, maybe 19.5....
Well if you REALLY wanna get technical, it seems liek the xflash is boosting 22 psi or so at peak torque. Getting a little brave on the boost are we? Safe much? Geez i really hope fellow nguyen doesn't get a bad batch of gas or it could spell disaster.

BTW, please return the AVCR that you stole from my friend back in HOUSTON. Thank you.

you hit the nail on the head homie. in fact, SO insecure that im gonna post 4 times in the next 10-15 minutes despite the fact that no one is listening to me anymore.

what i can't get over is your saying that "someone's gonna throw out their e-cack to make them feel better about themselves." Me thinks you're too late for that.

That.... or... the computer would pull timing and things would be peachy. ?

Add boost, pull out timing....no problems there. That was the point of the whole arguement man, the fact that the flash pulled timing to add boost, where as teh AFC could only add fuel to add boost, which is at the limit at 20psi.

You know that is really hard.

All Alex Alex does on this forum is insult people. No valid information or ideas are brought up at all. and of course he has to follow his message with hoping for protection



You are so insecure it's not even funny


Good luck my man I feel for you

Excellent results. You're the man, Shiv.

You don't even know the story so butt out. Doug ran off with my friend's avcr after my friend let him borrow it for his silver evo. Then he got a job in georgia and closed himself off all communications. My friend finally gave up and had to buy a profec A boost controller to replace the avcr.

Lol with that mentality i'd run 24psi and pull out mad timing and i'm golden. Ever read a compressor map? Something called compressor efficiency. I'll tell you this, 22 psi is blowing hotter air than you'd want.
Man i'd really like to see the timing figures at 3500rpms. Especially with 91 **** gas you have over there. 22psi on 91 octane? Getting brave I must say. Timing has to be something ridiculously low. I also guess nobody has a problem running static injectors. I wonder if anyone knows what will happen if "nguyen" runs race gas and boosts 24psi with a 10.1 afr? He's just going to be guzzling on the fuel pressure. That's getting to the point of running way too rich that'll hurt performance. Safe tune? I don't think so. Gsujeff55, you aren't lost in this technical jargon are you? That's why you went with a flash right? Because you weren't competent to tune your own car? Because you don't know what's REALLY going on with your engine?

Whoa dude, calm down. This is just Vishnu's tuning style and it seems to perform really well and safely. Also these results can be had on an XEDE as well as an XFlash so there's no need to bash on the flashing.

Please note that the 22 psi is still within the compressors efficiency range since it occurs early in the RPMs. 22 psi at 7500 would be out of the efficency range, however the boost taper Shiv tunes in keeps it in a happy range.

It's not just the 22psi i'm worried about, it's the combo of what timing at 22psi that shiv runs.
