Had a C5 Vette come in with a failed emission test and when I scanned the file, and looked at the readiness tests, it shows Catalytic converter and Evaporative Emissions test as n/a. This car doesnt...
Just wanted to put my .02 cents in. I have a Haltech dual-channel wideband on my Dyno Dynamics dyno, and it has worked flawlessly for 3 years. It uses a Bosch sensor, and I can put one in each bank...

Customer has a 57 Chevy with 05 drivetrain. The car was running, and he came into the shop to check into a lean code. I hooked up my VCM Editor to read, and it said "Security Access Denied". I...
My laptop is Vista, but I shut everything down, unplugged all my cabling, including the dyno hookups, waited half an hour, then started again. It worked fine, except twice during my reflash process,...

Very good. I thank you guys.
yeah, already went through all the preliminary stuff. Checked all the connectors and harnesses for chafing, etc. The customer's going to ship the ECU back to have it checked first. I really cant...
MAF Hz is totally normal until this happens. MAF sensor is still in stock location. Whats wierd is that even when the idle does this, you can drive off, and it runs pretty well. Best I can figure, it...
It has quite a few mods and a severe issue. I could use some help. It has a 2.8 pulley, ported blower inlet and t-body, and an ECU provided by ZZ Performance. Heres the issue.
When you start the...
So, I havent had the opportunity to mess with these cars, but will have one on Saturday to tune. What are the possibilities for this car, everything being stock? Will it be worth the credits in the...
