mapping advice please.
hello all as some of you no my fiesta is nearley on the road (nearley ,lol)
ive just finished fitting my go-tech mfi ecu and loom as i changed from megasquirt, the go-tech was mapped on a a focous rs with 750cc injectors. my injectors are 350cc and its a zetec turbo i no clearly the map is going to be compleatly unsuted to my spec but ive used it to get it up and running ive as i expected it was running lean so i richened it up a bit and got it to idal and my afr's are between 14-15 and my rpm is 900 but it just sounds rough
should i try opning the throttle a bit more and leaning it off or shutting it a bit ect im a bit lost now lol
i have never maped a car befor but im all ways looking into it. so i thort the best way was to have a go

when mapping try and find a pattern, map the bottom line first, so no boost just foot on the throttle and hold it at different mapping points,
when you have the first mapping point perfect, look at the next one, it is going to need more fuel obviously so give it some more, then take the engine revs to the next point and adjust fuelling untill its correct
now you can see the jump between them two points, its going to be similar all the way along so add the differece on top of the next point (for a rough estimate), just keep working your way along untill you have all the off boost point nice.
mapping in car is difficult, its much easier on a dyno as you can hold the revs and boost at any point for however long you need, but its not the cheapest way unfortunately !

Don't know anything about go-tec but with Emerald you can scale the whole map to allow for different injectors to save starting from scratch.
Is there not a feature on go-tech to do this ?

found this threed so thort i mite as well up date it since i started this threed i just pushed my fez to one side but i pulled it out the other weekend and had a play. it terns out my gotech is broken alltho i bort it under the inpression that it was fine it terns out that one of the coil drivers is broken
so my electrition took it apart and we used one of the spair drivers that is normaly used when running 6 cilinders and swaped them over............
still no luck tho its the ecu its self not firing the driver any one selling a go-tech mfi pro (should have stuck with megasquirt lol)
