SCT chip question

[Mustang363]

I've got one installed on my 94 gt and can change the tune's via a dial. My engine light came on, on my way home from the shop " Didn't go in with a engine light". The shop I took it too obviously claimed that it wasn't on when they had it lol so what I'd like to know is what specific device that has the proper software can i purchase that'll read the code's? Getting tired of spending big buck's for local shop's to do the trial and error method when a problem arise's cause they don't have the software themselves.

So you've got this set up?
If so, are you sure it's in the correct position?
Were any repairs / mods done that could have affected the engine light?

That appears to be the one yes. It's currently set on the 94 octane position. They only replaced the distributor, that's it.

Suggest you read codes n see what puter thinks has gone astray. Was timing set to it's prior value which I'm assuming is what tune was based on or we talking about can tunes vs dyno tunes?

Or buy one of these, cheap on Amazon or similar.

Well this is what I'am looking for.. But it can't be that easy, I've even had the car at Dasilva couple years ago for another problem and none of their personal hand held scanners would work. If it were that simple I'am sure they would have at least used the paperclip method and jump it. I will try it this evening and see what happen's, tvym

Did it. Is it normal to spit out same code twice? KOEO 511,115. KEOR 159

P0511 Idle Air Control Circuit
P0115 Engine Coolant Temperature Circuit
P0159 O2 Sensor Circuit Slow Response

Clear codes n drive it until light comes back on.
