help i've recently bought a ecu with a mines chip in it, its a 2c ecu and its fitted to a 94wrx with full decat,k+n. when giving it full throttle it boosts up to 20 psi but splutters like mad around 4500 rpm, if i only give it 3/4 throttle its fine, its fine boosting upto 15psi but if i give it full throttle it splutters like mad.

 

Hi Debbie,

If I were I'd get something done with the ECU fitted with the MINES chip. These chips are OK in Japan but over here its a tad dodgy. I'm speaking from experience, when 4 weeks ago my 95 WRX engine blew up (fitted with a MINES ECU). They're setup for 100RON and can be seriously putting your car at risk (overboosting, fuel cut, detonation). Get a boost gauge, AFR meter & knocklink fitted ASAP to monitor the amount of det you may be experiencing. Sorry to scare the sh!te out of you but after a £3k saving in a new engine I'm sure you'd thank me before its too late.

Have a look for info on here about a SCOOBYECU. Scott Taylor would give you more info.

 

agree with caz, i wouldn't use the mines!!!

friend of mine lost his engine to a mines ECU, it was running far too much ignition advance and the boost was far too high aswell.

sure it was fast........until it blew!!!!

 

My car was damn quick for 30 months until it went BANG too

 

20psi is far to high of you are running a stock engine. Infsct the standard map sensor can't even read 20psi, as it tops out and goes un-linear above 17.5psi.

the stutter you are getting at 4500 is fuel-cut due to the un-linear reading from the map sensor.

I would only set a WRX with a 2C ECU to 15.5psi (standard is 11.47psi).

Mail me if you want more info....

 

More bad news i'm afraid, my engine lasted weeks in the uk with a mines ecu. Running a standard one now! Can these not be remapped over here? At the time I didn't care as I didn't pay for a replacement engine.

 

Deviant, yes they can.
Mail me....

 

Sorry scott, This happened nearly a year ago - I told the garage I bought the car from to take it off, I didn't want the same to happen to the 2nd engine! Maybe was a mistake, aren't these ecu's about £750? Didn't know about scoobynet then. (another well researched car purchase!) Could be interested in a scoobyecu though - Next month cause MOT tax and insurance due this month! Holy **** I'm skint.

 

So I must have done ok then, mine lasted 30 months
