There are one problem with ALL of the aftermarket management systems. Not a single one of them has knock protection. The two things that kill turbo engines is knocking and F/A ratios.
If you have the right fuel, cold plugs and timing retard enough the engine will not knock. This is not the same for all engines and dyno operator must have done dozens of your model in your state of tune, to be able guarantee that it will not detonate while it gives max performance.
A/F ratios are often installation errors. A wire come loose or fuel pump is too small or pack-up.
In SA there are 3 companies manufacturing aftermarket ECUs, so there are some experts, but none specialize in Alfa.
I want a std ECU with knock sensors and will correct fuel outputs with a piggyback chip. I may fine tune the timing with the same chip but needs the ECU to retard timing when knock start. I don't think I will use more than 1.5 bar boost, but even then if something goes wrong(which happens) and boost goes above 1.5 bar the std MAP sensor will send zero reading to the ECU. That means no fuel and the lean mixture will destroy the engine instantaneous.
That is why I paid Steve to supply me with chip for 1.9 bar boost and I am also looking for a 3bar map sensor. But none of the items is available yet, so my 155 is standing like a white elephant, because I can not do the dyno-tune to set it up. Apparently the program was written, so if I can get that I will find some way to get a eprom written.
