Problem.. ---->


Loss of logging @ 7200 untill 8500
Loss of 80hp =/- @ 7200 untill 8500 then makes 40 +/- more hp...
During the time of the 7200-8500 the car has a miss fire like ignition..or pulled all timing...

What we have tried:

Different cam sensor
Different ECU
Different plugs ngk bpr8es gapped @ .020 and then again @ .016
Different tephra map or rom..
Ground on the engine to batt
Sparktech ignition instead of my Spooling up cop

My mods:
2.0l w stock valve and si dual springs
kelfords 272 cams
6265 turbo kit
Full blown dual pump kit
24 12 3.5 intercooler 2.5'' piping
magnus intake manifold w/ stock TB
speed density on stock computer
spooling up cop
Tial bov not sure what spring
Tial wastegate runs about 25 lbs without a boost controller


please tell me what you think is the casue of the loss of logging and loss of 80hp

the car ran 10.2 @ 139 but I know there is alot more mph and et in it..

 

Nothing? no one?

 

Logs would be more helpful

 

fuel cut double check that

 

if your log is disconnecting try a different lap top. Some time are high load, high rpm, high power, the electrical noise in the car can cause problems. I had a problem with my logs disconnecting on my old laptop (which wasn't that old), I was never sure if this was the problem but when I borrowed my wifes (hehe) the problem evaporated and this is on the same car, same cable, same day etc.

Try that.

 

Crankcase pressure too high, vent the vcover with large fittings -10 to a vented can

Also put back the OEM coils. You are only swapping one ign for the basically the same ign system, both not designed for the stock ecu

 

I have no idea what your problem is however in terms of your ignition system, they both work perfectly fine on the factory ECU so do not worry about the last comment. Have you covered the basics such as making sure you are getting enough fuel and do not have a boost leak?

 

How would the boost leak cause the computer to stop logging?

 

I got it to log on my computer but still has the missfire and 7200 on up. Cant figure it out...

Please help I want to go to the track this weekend..

 

Pull valve cover and check for broken springs. Check both the inner and outer springs. Had that same misfire symptom a few years time ago, chased ignition and everything else until i finally popped the valve cover off and saw the broke springs. Just an idea.

 

FIXED!!! I switched to AEM EMS went from running 10.2-3's and now with aem ems I went 9.77

 

Expensive fix.

I'm curious about the ROM you where using with Ecuflash with the issues you where having. Could you send it my way?

 

^this

Sounds like there was a conflict in the rom somewhere. That was a really expensive fix and honestly a dumb thing to do.
