ok i have a very tidy 1993 redtop smallport map sensor version and I'm putting it in a 1882 tercel 4x4 for a laugh also have a rb20 turbo and manifold for 4age bosch 044 surge tank intercooler etc what is the limitations with the ecu on these? can i put it on and run any boost on the stock ecu at all with a rising rate regulator and 98 octane fuel its all just for a bit of fun really don't want to waste heaps on a aftermarket ecu was hoping to get away with a rising rate regulator and a dodgey extra injector can you run gze injectors or any upgrade like that with the stock ecu? any info would be great thanks
