I just got a Diablo Chip for my car, and I've installed it the way it says I should, but when I turn the car back on, all that happens is my gauges reset, and then the speedometer goes up to about 130. Also the milage starts to go up as well. But when I remove the chip it runs just fine, any idea on what is causing this?

There is a problem between the chip & your ECU.

Did you buy this chip programmed specifically to your car & mods or did you buy it off someone? If it's the latter then you'll need to send the chip out to be reprogrammed to your car.

Other things to check is to make sure the contacts on both ends are clean and it's snug.

I had bought it off someone else, but I had already sent it off to get it reflashed for my computer code. I believe I have cleaned the contacts off well enough, but I guess I will try cleaning them off some more tomorrow.

Do you have a '99? There may be an internal part of the ECU that you need to solder. Diablo would be able to give you more info on that if that is the case.

 

[AuburnCougar]

I have a 01

One more thing, the red tab with Diablo Sport written on it, does it matter if that is on it or not?

 

[AuburnCougar]

OK I have done what everyone has asked and the chip still does the same thing....is there any way for me to find out if my computer had been reflashed with a different code?

 

[venom413]

I have the exact same problem? but mine is a Superchip. Exactly, How do you know if they changed the code?

 

[AuburnCougar]

I don't know how to find out, so I just got a ECU out of a totaled Cougar and I am about to see if I can switch it out, and if so then I will get a chip made for that one.

interesting, how do you plan on bypassing the PATS on the ignition? lol You can't just swap ECUs brutha.

Yeah I sort figured that out the other day, oh well just another $30 that I have blown on the cougar. Not the most expensive thing I have lost money on

You have to solder your factory ecu like this, the top two together and the bottom two connections. It will work great! I'm doin it tomorrow.

 

[AuburnCougar]

these are the two that you connect? btw what is your computer code? Mine is LAR1, and if yours will work after doing this, then I will go ahead and do it to mine.

 

[venom413]

Hey, It did work. When I went to test it down the road the light would flash and kind of kill my car so I'm guessing that I didn't salder it very good, so I'm goin to take it out and resaulder it, but it did make my car start!

 

[AuburnCougar]

let me know if there is anything else you had to do besides resoder.....did you also have premium in the tank?

 

[AuburnCougar]

venom....did resoddering the connections make it better, or did you have to do something else....I am about to fill up my car, and I was wanting to know, so that way I could decide on premium or regular.

 

[venom413]

Yep, that totally fixed the problem!! Drove eight hours straight and it's running great!!

I tried soddering the terminals this weekend, it was kind of hard to do, I guess using a pen style soddering iron isn't the best way to do it. But after soddering them together, I tried the chip and still no go.....I guess my FLM Dealer switched the code on me. Oh well.
