Diablo

[cruzincamaro]

Okay guys please bear with me. I got a Diablo Predator mainly to reprogram the cooling fans after a thermo change. The instruction are a bit sparse. There's a diagnostic section but it doesn't say if and when to start engine. I presume the engine must be running to run diagnostics , but when? I would hate to do it wrong and fry something. Anyone out there with a Predator who can HELP me? Would really appreciate it! Thanks!

I have a Hypertech that came with our car -- it reads codes while the engine is off and the key is in the "run" position.

pajeff02, thanks for the info, but i was thinking more on the line of checking my running coolant temp, since everyone is telling my NOT to put too much faith in the oem gauge.

I have a screen button on mine that pulls up the gauges. It has all sorts of display options. I took a look at the support page on their site and didn't see anything really helpful. Here it is: https://www.diablosport.com/index.ph...isplay&pid=187

Just got back from site u suggested. Found a forum section and posted my question. Waiting for reply. Thanks jeff

Used to have a predator tuner myself. You can run the car with the tuner plugged in the obd2 port and use it to get live data, including temp. Won't fry anything lol.

I agree that checking coolant temp with a scanner or utilizing an aftermarket gauge is the way to go. Other than in '98 models, the factory temp gauges are just about worthless imo.

Thanks derek, but do I start the engine after I get to the diagnostic section or does it make a difference?

[derekbuckner1]

If you set it up before you start the car, when the car cuts power to start the engine, it will reset the programmer. Plug it in after it's running.

[derekbuckner1]

And by reset the programmer, I just mean that it will power cycle. No harm done.

thanks derek & jeff. really appreciate the help.

Pajeff02 did you have a problem with your Ecuador kicking a p0010 code? I did and I am taking it back hupertech doesn't make a patch or anything for it

[pajeff02]

"P0010" is a camshaft position sensor circuit malfunction. Shouldn't be related to anything with the programmer that I am aware of.
