can anyone take a look at this and tell me if its good enof to run 14.5 psi on

 

its my cars chipped ecu rom

Looks no different from stock UK rom apart from the speed limiter is removed & they've made the knock maps identical to the normal maps.

so it wont be good to run 14.5psi as it wont be providing enough fuel?

Leaner Air fuel ratios and very advanced ignition maps, the timing map is really agressive...i wouldn't run it on my car!! But is kinda common to find such ignition maps with some JDM tuners.

 

Rev limiter set at 7400RPM.

lol so that means it can run 14.5 psi?

 

can u explain in more detail as im still confused lol

leaned AFR and very advanced timing is a recipe for detonation, I wouldn't be happy with it unless it had been proven ok on an RR

a leaner afr isnt always bad, unless its too lean. leaner = more power.

However unless verified with a wideband o2 meter then not worth the risk.

what prog are u using to open them maps? i'll i can see is squiggles

so i can use 14.5psi?

 

it will be at stock when im driving normally and put up when i want to boot it

 

the car had detonation before when i was using normal fuel, switched to v power and it has seemed to have cured it.

 

the igination was changed recently to accomodate the chip.

Mate my advice...if you already experienced detonation with this chip, don’t try to increase boost. You probably already have a socket, so maybe buying a reputable chip is the best option for you.

speak to John Dixon if you dont want your car to explode nuf said

ye ive pm'ed today, not heard back tho, how much are his chips

 

also if the chip was soldered on can i completely remove the ECU and give it to a shop to solder JD's chip on

 

thanks
