i have set the boostcut to this values to prevent overboost on Cold Engine and Hot Engine.

But Last weekend my Engine is Broken. i have a hole in the Piston near the trottle body.
I must now search for the issue... i think my Turbo is Blown up because all other 3 Pistons are fine, no Knock sparkles ...

This day i had the chance to drive a little bit around and the Plug Reading says is too Rich at 11.5:1 AFR...
I will try it a little bit leaner

Next little problem i have is the sparkplugs. I use Accel Plugs with 6-8 range. it looks fine on the top of the plug but the bottom is Black. When i use 8´s NGK the top is near White ...

thanks for the reply. In the past weeks i had a few Quartermile races so i have fine tuned the fuel and ignition maps. my target AFr is like you have postet. i run under full boost around 20 degree ignition. Boost is at this time max 9.2 psi.

Hi

After tune the non Vtec map on driving(it drives smooth with afr 14,8-13,5:1 afr) it seems to me that my Vtec map is a little bit too rich.

When Vtec switched on the Afr drop from 13,5 to 11-10,3:1 and it refs slow to 8k (faster then a non turbo vtec but i think it must ref harder).

The ...

the Basic Facts i must shown to is:

1. AF not over 14.7 on low load (closed loop operation)

2. AF not over 13.8 in medium load (open loop 50% tps +)

3. AF not over 13 in high load (Vtec 80% TPS +)

4. EGT not over 850 °C (im not know this in °F)

This has telling me my engine builder.

I have ...

it will not damage my new engine when its idle around 15 afr ?

Wastegate is set to 6 psi but it goes up to 7-7.5 psi.

At weekend i will drive it and post my map and a datalog of the 3rd or 4th gear pull.

Im a little bit scared to damage my new engine
