If I plan to put a small turbo (to3 or summat) onto my Holden EFI 202 I would need new management - what are your suggestions?
New management ..... Yes. What that means is that you will likely need to do new injectors and some sensors as well to go with your new aftermarket ECU.
They will all work, from Microtech up to Motec. Pick how much money you want to spend. Given that you probably don't need too much in the way of tricks and gimmicks you could easily survive on Microtech.....it's much superior to the old factory ECU anyway, even if it is not up to speed with the big guys in the market.

Thanks GTSBoy, the Microtech ECU looks good. I'm just waiting for a reply from them about price and stuff...

LT-8 retail at $1095,
LTX-12 retail at $1495
software and dongle $100
Do the VK run a electronic ignation?? if so just use a LT-8 running a waste spark setup, or you can go the more expansive way of a LTX-12 with direct fire ignation.

How about I leave the engine carby fed. That way, it'l be alot easier to tune
I've having had much expeirance with vk efi.
Can you tell me what senors this set up uses e.g MAP sensor etc?

Depends on how you set it up,
most computers use a map sensor, you can set most to run off TPS until the computer comes on boost good for cars with big cams or multi throttle bodies,
Which is better map or tps?

a hotwire mass airflow meter is the best setup in regards to engine changes as they are more tolerant to cam changes,etc
Russell, there are not too many aftermarket ECUs that will read AFMs.
It is a fact of life that we usually have to resort to MAP load sensing when we go Microtech or Motec.

I know a lot aftermarket systems use MAP sensors,I was stating that an airflow meter is better as it more tolerant to engine mods without having to modify the computer program.
That is why if you say whacked a different cam & exhaust package into a VN - VR Commodore it wouldn't perform better without changing or rewriting the chip as it would run too lean.
An air flow meter has a far wider tolerance as far as exhaust systems,etc go.
Yeah, but look at the rest of the thread and realise that it is not pertinent. :rolleyes:
