Converting Silvertop to MAP/ DLI Ignition for 20v

i take your using the quad throttles? if so you'l probably run into some fueling problems, using map vs rpm only.

isnt this along the same lines of how the "MAPecu" works?

Yeah same deal, except costs me less than US$400+freight and the main feature for me is the DLI conversion, getting rid of the AFM is just a bonus..

Not sure what quad throttle has to do with it? Unless you are referencing how I tap my MAP sensor. I have made a custom plate on top of the quads removing that ugly vacuum rail and I have my MAP sensor off that, so its a sum of all cylinders so it should give a MAP reading.

Enlighten me, if your statement wasn’t to do with this…

sorry cut that a bit short. when you reach around 50% throttle the map will be atmospheric pressure, from that point all the way till full throttle. so because map vs rpm doesnt equal aiflow in this case. you'l either have a lean patch or rich patch. depending how you tune it.

best way to fix it would be too use tps too add fuel. once you have gone past 50% (or whatever it happens to be) throtttle. thats if you can do that of course

or tps only. but wont be so great

hey jormos90 i have D.L.I converter box i got from Ozzy last year and it does exactly what your trying to do by making two IGT signals from one and run waste spark. i payed 250 AUS$ for it. i wanted to copy it so i could make another one for another engine conv. but the guy who i got it from has taken the serial/I.D numbers off the tops of the chips. is there a way to find out what chips it uses?

i'd send the unit to you to have a look at but i need it to run my daily car.
