Engine runs great! but...the transmission however is not working!
The reverse lockout is inop. Skip shift is turned off, so unknown.
speedo only reads 40mph on expresway
I checked all of the harnesses and nothing is pinched, so even though the ses light was not on I pulled codes and have a TCC code...in a T56. I think I may have gotten an automatic PCM because the tach works fine but the speedo is way off. It reads 40mph on the expressway

MadZ28 tune, he does my tuning.

 

You really need a way to upload or download your program to find out yourself or have one of us help you, but the guy should be able to verify what he sent ya. Maybe someone else got one that was supposed to be yours.

 

got a DTC90 in the PCM, thats a TCC failure in my M6...

I also have ABS codes on but that was on before the tuning changes
ABS HISTORY CODES, NO CURRENTS
021 LF NO SIGNAL
025 LF EXCESSIVE
026 RF EXCESSIVE
032 LF OPEN OR SHORT TO GR/BAT
047 LF ABS MOTOR FREE SPIN

 

Hey there i have a the same setup but my heads have 2.00-1.56 valves and my manifold was matched to the heads. I put 370 HP and 345 TQ to the wheels.

Seems low and its been dyno tuned. Any idea what yours is running?

BTW i bought a set of 643 stamped heads from you a while back-- funny we have the same exact setup almost. Nice car.

 

wow, that long ago! those were my original heads off my car! no dyno yet but if you want to come drive it and see we can see if we can feel a difference...

I work in Northville now

 

I moved to Texas last month for a job-- I will be back in July though. My car is still in Michigan. Goodluck with the build. How does it run? Feel strong? Mine does just didnt get the numbers expected but it was still making power at 6800 RPM. Lloyd said it would do aprox 400 RWHP. I had the car dyno tuned at Motor City speed dyno using a wide band O2. Rich Gala ( I think is the owners name) Is a great guy. They do alot of LS1 cars. my car ran 13.001 @ 112 mph on street tires.

 

call me or PM me when you are here we will meet up and try out the cars!

 

Ding...ding...ding....We have a winner!

The same exact thing happened to me this past november. Turned out my dyno guy had it programed for an auto instead of an M6.

 

It was a auto PCM and the tuner took care of it and the car runs amazing now!
