Can some one tell me why after my stage one package of two weeks ago my engine light has just come on.
I know nothing about cars, and I want to know if it is safe to drive the car off boost till I can ring my tuners on monday.
Any advice would be gratefully accepted.
Thanks.

Any chance you can tell us what model and what year it is please? and what exactly is a "stage 1" package?

Does the CEL go out after about 5 starts ? and is it a Bugeye (MY01/02) WRX......a notorious Random CEL generator LOL

Sorry, its an 07 year 2.5 Hawkeye Sti and the car has uprated fuel pump, panel flter 76mm Milltek exhaust with sports cat. and of course a custom remap.
The car appears to be running fine, just the light is on steadily.

Probably due ti the miltek exhaust wit sports cat, it will be okay for MOT but outside the parameters set by Subaru. Years ago tehe was a CEL light fix unit but cannot remember where from. Speak to where you got the work done for advice, they may be able to fix it in the ecu. Get this annually at MOT time.

So its ok to drive ?
I will keep it of boost as a precaution.

I have same trouble wi my 06 hawkeye and i have just got it back from having a complete engine rebuild just wiating to get remap once i run it in
so was told it would be ok as long as i keep it off boost

i have the same problem my 03 sti has an ecutek remap and upgrade stage 2 355 bhp and the engine light is always on cos theres no cat and the emissions make the sensor light come on apparently

I doubt if it's a de-cat / sports cat issue as the Tuner usually maps this CEL (P0420) out so it never appears

shouldn't have engine light on.. could be anything thought before someone plugs in and checks the actual code.. emissions should be mapped out but can be missed..

whomever mapped it should turn it off... if you let them know it is on, assuming just emissions

scoobykarl666

its set up so i can turn it on and off with a double press of the rear window heater button while accelerator is fully down

Thats the low / high boost function typical of an EcuTeK map ............. not related to the CEL

Shaun

right thanks for that .maybe the ppl i bought it from didnt explain it very well then

The Veteran

Thanks every one, I think it best if I leave it parked up tomorrow, then speak to my mapper on monday, (he is one of the best around) the car has been really great,so hopefully its not to serious.
Thanks again.

The Veteran

Further thought, if the emissions are mapped out, as already suggested, is there a chance it may not show up a more serious problem developing.

Exactly !

Drive it like Grandma till it's re-re-map'd.....

"By one of the best" who just may have slipped up, possibly or there is a random fault surfacing....

I had the same problem on my 03WRX after it had a up pipe, sports cat and remap by Zen, i Think it is to do with the Oxygen sensor in the up pipe, luckily I have a tactrix cable and software so checked it out, and did a search for CEL fix, I cannot fully remember what I did but I had to put a resistor in the plug to replace the sensor, that was 2 years ago, no problems and no engine light

no you can turn just the emissions error codes off.

would hazard a guess your higher boost map is triggering the overboost CEL and you flip it to the low boost and drive it and the light will then go out.. there are two boost limits, one for the CEL and one to fuel cut, assuming it is an 01~05 car.
