I've got 3 PRV 24v engines, a standalone ECU and a Rotrex supercharger with oil cooler cluttering up my living room!

The only one answer to the MANY Many replies, Its the only question and answer im posting, so dont ask for anymore replies
Forum; Shame the GTA doesn't respond to a piggyback units like the japanese cars do...
Things like Dastek, Unichip etc, can't remedy the over correcting ignition retard and fuel enrichment caused by the high inlet temp air sensor..
Dastek;Yes it can, it has two temperature inputs that can be linked to any of the maps inside the Unichip, so timing & fuel corrections can made versus both water & charge temp, but rarely are they needed unless there is a specific problem with the cars compensation maps (pretty rare)

And how is it going to correct the fuel when we are at maximum range on the map signal? There is no more fuel to give...
And how will two settings be setup when, the car is instantly peaking the air temp reading on the RR.

Also, you have to remember, there is no useful mapping after 14.7psi, as the GTA mapsensor is a 2 bar absolute sensor. If the RR map your car for 20psi, it will fuel exactly the same at 14psi, so if you run a boost pressure lower than 20, it will overfuel massively...
This is why the Unichip reads from its own 2.5bar absolute (22psi boost) pressure sensor, so that the Unichip can read beyond the original design of the std car. We could use a 3.5bar (36psi) absolute version if required.
