Mines computer problems???

[4bella]

I have an r32 gts-t , i just bought the car 2 weeks ago and my first test drive on it was sweet. but once i actually got the car it just seemed really sluggish especiialy at low revs and first and 2nd gear.... i was told the mods on the car wasa gt28 turbo, fuel regulator, mines computer, boost controller, high boost set on 18-20 psi.....someimtes when i give it heaps the car jerks around alot and is very sluggin in low revs as in very slow... i was told its the mines computer coz it runs very rich fuel and is designed for japanese fuel only....does anyone know how to help me please?

Turn the boost down to 12psi and see how it runs then and try octane booster

If you have just purchased the car change everything; oil, oil filter, fuel filter, spark plugs etc. Who knows when or sometimes IF these have ever been changed. Have you done a compression test on the car ? With such high boost, and a Mines computer, who knows if you have piston trouble or similar.

The Mines computer Id suggest is leaning the car, NOT making it rich. Jap fuel is 100RON and cooler ambient temps... having a Mins comp in a Aussie car with lower octane fuel and hotter temps, your not giving the car the correct mixture in relation to what the Mines wants your car to have.

I wouldnt go hammering your car until you get it sorted. You say your car jerks sometimes? Again, it could be getting plently of air but not enough fuel.. not good. So id look at fuel filter, maybe getting your injectors cleaned, lowering your boost, chucking the Mines comp. Hmm, what type of fuel regulator do you have? be worth checking that out too, it may not be delivering the fuel you need.

Would be worth putting in on a dyno, just to see where things are at also.

My car came with a mines ecu - used to run very rich at low rpm - and also very lean on high rpm.

So I changed to a Power FC. No probs now.
