As far as senders and ecu are concerned, would they be different if i used 3 throttle bodies?
Or would the same electronic set up handle either fuel set up?
Sorry, probably stupid questions ;D

Just so long as the output is wired to take the correct impedance of the extra injectors. If you're building yourself a Megasquirt, I think they give you calculations you can do. I know Adaptorman had issues with his Caddy and the injectors not being fired right because they were the wrong impedance (resistance).

i don't think you will get the same charge robbing problems on a 6 as you will with a 4. due to the differing firing order. one person i can suggest contacting is matt thorne at mtech automotive.

Batch fire is more common on early injection that sequential. At least you get a fire per TDC but I still think it's worth checking what happens at different duty with a siamese port. It will probably work out ok, but for the sake of a bit of maths it's worth doing. If the batch fire is per cycle i.e every other TDC then I'd think there's a likelyhood of issues, but even the very early electronic S12 system was every TDC...

yeah, ill deffo be doing more research before any comitments. As i say, car may still yet get sold, but adding FI and forced induction to an ancient engine design is high on my 'to do' list anyway so the knowledge is all good. I may be moving back down early 2010 30psi, we'll have to chat more over a beer ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) Didnt get time to meet up last time i was down, 'family issues ![:(](//storage.proboards.com/forum/images/smiley/sad.png) '

That's ok Graeme, I guessed you were busy when you were down. Will it be a permanent move then? PS - Check down the back of sofa, I'm trying to raise some cash here for charity (shameless plug) ![;)](//storage.proboards.com/forum/images/smiley/wink.png)
