16v 4AGE quad throttles - stock ECU shortcomings Fri, 08 July 2005 22:30 Go to previous message
I've got a smallport 16v 4AGE, and have a set of 20v throttle bodies. Looking at putting the two together, and have been looking at info about getting the two to fit. At the moment I'm inclined to do it the way Ben Wilson has done it - to get a stock manifold, cut it and weld a plate on to mount the quads.

So yes, getting it to actually fit on the engine, I think I have that sort of sorted in my head.

Now, computer. I've read somewhere that the stock computer can run the quads (although not spectacularly well). Everywhere here on Toymods I seem to read that it can't, though, and that I'll need an aftermarket computer of some description. What are the shortcomings of the stock ECU? Is it the fuel? I'm guessing it would run too lean, since the engine would be getting more air, and perhaps the MAP readings may be a bit strange as well with such a short manifold. If it's only the fuel that is a problem, would a piggyback computer (like the one Jaycar sells) to modify the MAP reading fix this?

Aftermarket computer would be the bees knees but budget isn't super, so if a cheaper option is availble it would be nice to know Smile

If a piggyback fuel computer won't fix it then I might look into the Megasquirt computer, would it be able to run just controlling fuel? Or will MS2 or similar be needed to control ignition as well?
