Im bored n been looking at that excel set up but doest really go into details lol it covers the manifold part but what ecu? What other sensors do you need I'm thinking after I get passed my 2 Regos n c card I'm going to have a crack at it or carby turbo just so on the way home I can keep up with a v6 bommodore lol

doing that set up as we speak. Not that much to it. its all there. i believe i can use same ecu but maybe bit of dyno work.

Oh really do tell what have u done so far?

You can use any ECU you want.

Buy a $1500 ECU, or use a factory Datsun ECU. In the USA we mostly either use MegaSquirt or the Datsun 200SX EFI (S110 ECU).

Dont really know that much about the in's and out's of it... I am not a mechanic or pretend to be 1. basically have 2 full hyundai efi set up's including loom's and cpu's. Went into the shop yesterday where my heads are getting done. I have 3 motors getting built. 1 efi blown , 1 efi turbo and 1 quad bike carbs. The efi's have held me up as my block's are all done... As far as i can see, the the hyundai manifold has been welded up abit and then grinded back out about 5 mm to the left. Made a copy of a template (thanks Chris) to suit h89 head, has been welded to manifold and grinded out to match the porting of the head. Running standard 1.5L hyundai injectors for now. And as for the cpu, you can run pretty much what you want.And how much your prepared to spend. If the hyundai cpu's become a problem, I have a box full of nissan 1's. No matter what cpu you get , you probably will still need to get it dynoed. So I am working with the cheaper cpu and spending more on the dyno. Sorry to be so vague.

Where do I get this mega squirt

google it

When u say run any ecu just thinking ok iv got the a12 stock.. If u ran the Hyundai 1.5 ecu n injectors would't it give it to much fuel? What other sensors do u need.

thats why you get it dynoed. i think an A12 would handle that size injector no problem. if not you would get a new set for a few hundred there abouts

For MegaSquirt, click this link: MegaSquirt.

If you use the Hyndai injectors and sensors, it should run very well. You won't need to get it tuned. Just make sure it's running the hyundai spec fuel pressure.

Same with the Datsun ECU, with Datsun parts and spec fuel pressure, it will run correctly.

The factory ECUs are smart enough to adapt themselves.
