In my experience the generator generates a horrifically rich off-boost and scarily lean on-boost table for the 3sgte. I will soon be writing a how-to on the 3sgte (ST185 engine with TVIS) and will include some half decent base maps to get people cooking but I wont give out final maps simply because ...

It will stumble but you might not hear it unless flying or idling. If i give mine a blip and burn when on the decel i cant hear it, but if im idling it occasionally stalls and on the highway it makes an "off throttle" feeling for a second. If you arent getting previous numbers up then it will be ...

Closest you could do would be an identical sensor mounted X degrees out and set up MS to use that.

All you need to do is set up MS with its own sensors and take control of the injector, fuel pump and ignition wiring and leave all other connections to the old ECU in place. I did this with mine while i was en-route to full plug-and-play swappable. Worked fine except the idle control of the stock ...

Dr Hess - you sure its 5 with a drop to ground? I used it as a tach input signal to the MS and im 99% certain that on mine it was a 0-5v digital pulse upon spark.

I also get best idle around 20-30 (lowest kpa and smoothest) but it seems whacky so i run 20 to be at the lower end of whacky. But then when the stock ECU runs and I use a timing light the mark vanishes out of view so I assume 20+ is fairly standard.

If you look at these maps of my car (supposedly ...

I got this running just by 'T'-ing into the IGF line and using a 1K resistor before it reached the 'squirt IIRC. This shared the signal with the original ECU and all were happy. You may have to tweak the resistor size to get the right compromise, big as you can go without the MS losing signal.

I always get the little stumble when i hit burn but i must say ive not made sure i've tabbed every time - I'll try it now on my stim. Cheers

I spent the morning totally confused. Id adjust my ignition trigger angle, burn, hear the engine stumble and pick up again and have no change in angle on the crank. Id change it again, burn , no change. Do a Fetch and it comes back with the original number. Hmm. So i tried burning, closing the ...

Can you checkout my MSQ and see if ive done something stupid please? Its in my datalogs folder below, sorry to be a pain in the bum. I'm using the stock dizzy on my yota which has a 24 tooth wheel on the cam and a 2nd 2-tooth with two sensors also on the cam. I'm struggling to set it up correctly i ...
