So removed the pressure limits and re bled the intercooler and on the street there was a noticeable difference. More solid boost curve and no kr.

I've had 3 customers show up for a tune now with psi conversions ecu, and every single one the trans tune has to be set super low ex. If I want to shift at 40 I have to tell it shift at 20.. also...

It's very useful because you can actually see if it will be spraying on an open valve or closed. Normally only need 10-20 in the ect tables to clear it up at idle, it's very simple like ghuggins...

I used dsteks eoit calculator I looked for weeks for it but it really helped me with 17* of overlap sooo your welcome

So recently every time I get in 4th gear at wot and start getting around 8lbs of boost I get the service traction , service active handling, and service abs... Has anyone ever found a solution to the...

Have you ever had problems with the o2 being too cold and not reading correctly. If I'm am driving I can get them to be great but if I stop and idle for 2-5 mins the trims go crazy. Been reading your...

Yes I'll do it tomorrow. I know it makes no sense only conclusion I can think of is 15* of overlap giving them raw fuel. I attempted to tune the o2 by logging mv vs afr and 825mv is 14.5-15 afr but...

So I tried going back to the stock os and its fine now so it is strange how it would not run the same ve table on the 2 bar os. I have to do a little more vve tuning I am at +-5% now. Also I may have...

How would spark be causing a lean condition? I just don't know why it only happens on sd and maf together never when one is alone

So I've tried the gain and gas tab on impact and evap and still not any better. I'm at a loss on why its not getting better. I've added up to 30% and it won't change at all on tip in

Idle air was turned up to help it in SD and idle timing I like 20*. I went with the 2bar os just so I didn't have to use the bluecat stuff car runs great but for some strange reason when sd and maf...

No leaks found on smoke test and car runs perfect on sd only. I am going to rescale the maf again

here is the tune file. should the impact tables be lowered since it is the amount of fuel hitting the port wall. in turn making the ecu inject more fuel?

Ok I will look at the impact and gain I'll try maybe 10-15% more and see if I get a good result also going to smoke test the manifold today. I've heard alot about them not sitting right and leaking.

Just installed a fast 102, car is on a 2 bar os and ran perfect now have a lean spike any time you tip in from low rpm did tons of ve tuning and maf....

ok thank you i hope this helps others with the same questions. also would help it this was added to the vve tuning write ups.

thank you i hope this helps other people and for final clarification should this be set back after ve tables are calibrated?

Problem is I can't for another month I am away from all my stuff. It's like something is causing the commanded afr to jump around and not stay steady and 14.67.

hello, i have searched and searched and cannot find i good answer for vve cars and getting a steady 14.7 commanded afr at idle. my current car is a 2010 c6 ls3 with 236/248 cam, longtubes, and...

So I tried disabling spark smoothing and its is listening alot better I mean alot better so I'll try in the morning to play with timing again but possibly spark smoothing is my key

Also I am suspecting that my vararam intake may be leaking some air after the maf so also gonna do a little smoke test today
