Polo GTI APR ECU Upgrade

Good Stuff Hooti - We have been on the dyno all morning with the new "base line" car - stage 1 vs stock, all temps logged & recorded at 3 positions - intercooler fitting happening now for round 2 of tests.

I'm keen to see what yours makes on the dyno with intercooler, intake tbe and the V2.0 software. APR usa still haven't changed their website from the old V1.0 graphs.

I'm literally about to change software to either APR or REVO so I can switch maps, but so far I've only seen the revo graphs

will see if they can mod the V 2.0 graphs, we have them.

Problem is, not all cars can take the V 2.0 program (it depends on the ECU part number which defines which fueling system is installed on the car) - if your car has the late fuel system, its all good, if it has the early one, you can't extract as much power.

Sent me an email & I'll see what dyno's I can dig up for you!

Much appreciated Guy

My car had the later fuel system so is fine for the V2.0 map.

Email sent, much appreciated.

Question though, if for instance you had a car with tbe, intake and loaded the stage 2 map onto it. If you then got a car with the above mods and an intercooler can you tweak it to run more boost or timing etc or is it the same stage 2 map regardless of eztra mods?

Any luck wth these dyno graphs Guy?

Have ApR considered a reduction in size of the supercharger pulley. It something a fewchuys in the UK are now looking into so we can boost the midrange

Sorry, back from holidays now - dyno's are on your email - that car only has software / intake / intercooler comparisons (no exhaust).

We have no need to alter the supercharger pulley @ this stage as it is underutilised in standard form
