I just had a company program a few car's here at Lund Hummer. WOW what a differance in pick up. I am now programming H3's that have a Volant Cold Air Box and a Volant Exhaust System. I am sending a H3 to the Dyno Monday to see what we are geting. I know by the seat of the pants it is very impressive!

 

Let us know because the power programmer did nothing on my s10

 

I'm going to have my PCU reprogrammed..It will be completetly remapped for the most optimum performance and HP...Once it is done, I'll report back here with all the details...But I have to ship my PCU off to a lab.

The problem is, I don't quite know how to disconnect the PCU wiring connectors..or at least I'm too timid to unplug until I know what I'm doing...
Anybody out there know how these connectors to the PCU come apart?

 

Looks similar to an airbag harness, remove the red strap (these just ensure the connections are tigh), then the other piece should just depress and unlock like any other plug

 

Thanks![sm=smiley20.gif]

 

Dennis becaufull sending that out if they lose it your ****ed insure it.
Some of the car they send you a chip you just replace but Toyota you have to send out to very scary if it get lost or damage

 

Thanks Mark..Good idea..What are these dude's value?..$1000.00 or more?

 

I say more and time you get one to replace it might be for a long time
That why i never sent my 4runner out i think the 4runners where 3,000 to replace it

 

That PCM price is way out of line. The PCM cost for the Hummer H3 is a whopping $340.00 and is very easy to get. The Highest price PCM for a GM that I have seen is $900.00 dallars. Before we scare everyone we should contact our local parts department.

 

Jaya any word from the Dyno?
