What Computer Is This?

[luke r33]

hi just a quick question , i have a skyline r33 gtst ,with front mount ,3 inch exhaust, and a CENTRAL 20 ECU??? any information on this ecu would be appreciated . i am looking at doing more mods (high flow turbo, bigger injectors,etc.) i am after 250 rwks and need to know is this ecu up to the task or should i get an apexi pfc. cheers!

central 20's a tuning house in japan. Its just a stock ECU with some tweaks to suit your car (might be something as simple as a speed limit removal or fuel cut removal or it could be a whole new fuel map). Anyways, you'll need a full retune if you're goin with those mods to get the most out of them. If its retunable, and you can find someone to do it, use that. Otherwise turf it and get a PFC. Its not worth anymore than a stock ECU... actually might be worth less, coz the only use anyone will have for it is if they have the exact same mods as your car.

cheers mate yeah it runs really fuelly and has no speed limiter and rev limiter hits 8000rpm, got a dyno at uas and bloke said he doesnt know what it is and you wont find any one to tune it so i might have to go with power fc

might wanna talk to Dr Drift in melbourne... he works with ECU's that have been modified.

i live in sydney near unique auto sports which are experts with power c so that might be the way to go

Take the top cover off the ECU, take a pic, and I'll tell you if it's easily tuned in real time..

no worries i will post up the pics tomorrow

my old ecu chipped by garage saurus in japan caused my car to melt the ringlands on a few cyclinders, make sure its not detonating or runnin lean, in the end bite the bullet and get a pfc i reakon,

sorry about the quality the best i could do

[luke r33]

beleive it or not this car made 197 rwkw at unique auto sports on standard boost standard exhaust , just front mount and this ecu as far as i know every thing is standard

[luke r33]

must be something done to this car i dont know about?????

it's not easily retuneable i'm afraid. I would go with the PFC.

[luke r33]

the central 20 chip looks like it plugs into a socket they have solderd in there if that helps any?

send pics to dr drift and ask him if he can retune em (from memory I don't think so)

but yeah, so much easier and better to go with PFC.

Sam retuned my C20 ECU and he said that it was the first one he was successfully able to remove the chip.

[funkymonkey]

was he able to remap it though? when i spoke to him last he said he could do R32 and R34's

Can do, just not yet, I have an eprom ECU of my own for live tuning, and just need to get hot of the hardware to tune the H8/534 processor style chip to burn the map onto when we're done.
