Wirking on an 08 Vette and installed a tick master cylinder.

Need to reset the clutch position and am having an issue.

I can reset the Clutch in position (fully disengaged) no problem. But I...

Hey Guys.

Big Problem. Upgraded my OS to 1 Bar MAF today for RTT. Well, turns out this OS is not allowing the PCM to provide grounds for the Efans. Found this out as temps climbed to 260!...

Yep. Cost $100...still not sure if it was worth it :shrug:

I thought I posted up the resolution...guess not :doh:

I upgraded the OS to 12212156 from a 2002 I found in the HPT Repository. After I did this, everything functions as it should.

From all the...

They only run when the engine is started.

They respond to the startup delay as well.

Read through your posts. My exact issue.

So a new OS should solve my issue? Will applying a custom OS fix the issue as well?

Nope. Checked the status bits and all looks good. Thanks for the suggestion!

Need a little help getting my efans to work correctly.

Well, had a buddy come by with a 2007 truck, and I cannot connect to his either. However, I can connect to my 2001. So it's a software issue. This makes me feel somewhat better, but I still have a...

Now it won't even locate the VCM. All fuses are good. i unplugged the underhood fusebox and disconnected the battery. No dice. I'm stumped and it's not my truck so this is what's really bothering me....

Hey Guys,

I have a problem. Trying to tune a 2007 Silverado. Had flashed the truck successfully several times, and then during one flash the TCM write failed and now I can no longer flash...

Hey Guys,

Farily new to tuning, and I can't get my truck dialed in. I feel like I'm missing 20-30hp atleast.

Best I can manage is 9.12 @76...

I've driven it about 50 miles since (mostly city) and it's still working fine.

I refuse to pull the 60e again..so I'm hoping the whole setup last long enough til I get enough for an 80e swap.

Yeah I logged it. It was saying "locked" but the converter actually wasn't.

But get this..I went to drive it and see if I could get it to throw any codes..and it locked up. I haven't changed a...

It's just their Restalled Trailblazer one. 3-3200

I have already posted the apply/release speed above...And this is what is in the release table.

MPH is given, and the 100 is % of throttle input needed before the converter will unlock. Stock...

In trucks, the release tables are TPS % not MPH. 100% is the stock setting and I have verified this is correct with other trucks that I know lock the converter correctly.

Well, new TCC and PWM Solenoids didn't fix the issue.

Anyone else notice anything in my tune that could possible cause no lock up?

Thanks!!!

Trans temp is ~170.

I have ruled out tuning issues and think it is an internal problem. Will be tearing the trans down next week.

Thanks for the replies guys.

I must be missing something..because no where in do I see where the release is higher than the apply except for 2nd gear? And I do not want it to lock in 2nd.

Thanks!

Hey guys,

Ran into a problem today..

My converter (Circle D 3200) will not lock up at cruise. I can manually lock it up with HP Tuners, so I don't believe the converter is bad. No misfires, but...

I hooked it up according to this link, which doesn't show a separate ground, only the ground from the WB to the MPVI.

Related question..can you just simply run the black ground wire to the MPVI Pro pin #5?

This is how I have mine, and just want to make sure I am not doing it incorrectly.

Not afraid of wheelspin..trying to make some happen. lol.

I have attached some screen shots, hopefully this makes my questions a bit more clear.

Thanks!

Hey All,
