Madazbpt

I have a g3 link installed into a mazda familia GTR, and I'm having issues with the alternator not charging the battery. Two different brand new alternators installed and still same issue. It seems to charge again when going over bump. The shop seems to think the ECU is at fault, what would it be and can the ECU be fixed? Or will I have to replace it?

Recently had my Mazda BPT dyno tuned but they didnt adjust the cold start on the car and it runs too rich from cold where it actually makes the car pulse likely a rotary on idle when first started and stinks of fuel, but once car is warmed up it runs mint... What should I be setting the crank enrichment, post start enrichment and warm up enrichment to? I've checked the standard "LEM_G3_SAMPLE.pcl" and it's got the same tables that map uses for the crank enrichment, post start up enrichment and warm up enrichment has. Any help would be good, the car just runs too rich on cold start and can't be good for the engine for every day driving...

Where do I wire the IAT sensor into? I'm running a g3 link in a mazda 1800 dohc turbo. what wires am i meant to tee this into? thanks

I'm currently about to get some intercooler piping made for my mazda familia gtr build but I haven't got an IAT and want one for when my g3 gets tuned on the dyno So my question is: Is there a factory IAT I can use out of another car to adapt into my piping? If so, what car and model can i use one out of? just trying to cut costs really cheers
