This is acutally the first 996 I have heard audibly knock on the dyno. Just take care untill you/we can test with the 5 bar in to see if it corrects the situation.

Like we talked about yesterday run the gas out and fill up with fresh 93. Hopefully it was just bad gas.
Tony,
I did forget to mention that I have gotten an engine light. Code was for secondary air system . this happened with the old ECU and the new one.
Could this be an air leak ? which is contributing to this situation?

Maybe a cracked F-hose? I had the same code long time ago and replaced the hoses and diverters and never had the issue again. I see you have diverters so Im leaning to hoses, especially the F-hose from previous thread searches.

Wouldn't the car pull timing if the AFRs are above 12 or if there was bad gas? The reason I ask because on my dyno runs the car pulled timing on all 3 runs around 5,000rpm.

Martin-

Just install the turbos and see how it runs...You'll be surprised how much the ecu can adapt

Detonation can happen faster then the ecu has time to correct for....

I think ... if memory serves ... some dude named "KPG" ran 518 AWHP / 580 AWTQ on UMW's K16/K24 ZC (Kevin's programming of course) ...

Great thing about it.. he didnt have to ship his ECU !!!

Ari, it was 512 AWHP and 565 AWTQ on a AWD Mustang at 1.25 Bar and running only pump gas. I will try to find the graph, but suffice it so Kevin's turbos work best with his programming.....

Ahhh... 512AWHP / 565AWTQ ... my mistake, I stand corrected ... not bad for 1.25 bar and pump gas...

I'm curious how these "modest" sized k16's would run with race gas and slightly higher boost ...

Can anybody chime in?

Well My computer is going back to Upsolute today, and as soon as I get it back I'll be ordering Kevin's tune and a 5bar FPR. Kevin and I spoke on the phone for over half hour yesterday and I'm pretty much done with my search.

a 5Bar FPR is $275 and about an hour to install. So why wouldn't you safe guard your investment?

Mike

Well, seeing as you have the same setup, maybe you should try the race gas file. The funny thing is that during my whole time with this setup I was nursing an intermittent Bank1 VarioCam fault that turned out to be terminal eventually and Porsche paid to have the motor R+R and the VC module and sealing rings replaced. I did have the race file and was on my way to the track to run it when the VC failed . It crapped out as I turned into the track, so I never got the chance. When the VC fails the car idles like a bulldozer.....

The hp@50 should be 15.4 when testing this car. Figures may be slightly off.
