Remapping - MK4 R32

[JVLR32]

Or supercharger (I know a lot of people don't like it but...)
Guy, with the APR chip are you able to retune it for cams and forced induction setups etc?
Or is basically having to go some kind of Motec, Haltech piggy back or other replacement ecu the best option here?
Thought I'd ask these kind of questions now whilst the topic comes up.

good questions mmmm yeh would we get more out of a piggy back setup?

Stock for stock maybe a little but nothing to justify the extra cost of purchasing the ECU, getting it fitted and tuned etc. But with the type of mods I listed?

Is there a advanced throttle body kit for a R

[Guy_H]

It could be retuned, but we would need a good case of how many & the same mods.

A piggy back would probably be going backwards, I have seen many "piggy back" systems fail to make the same horsepower on ME7 cars, and struggle to run nicely at all (only the couple I have seen). Full stand alone would probably be the go if you went for radical mods!

Question...throttle body,manifold worth it all not?

So basically as a one off thing, no unless one was willing to shell out the big bucks for the time and effort?

Correct - Time tuning costs dollars, so one off mods = uneconomical.

If we have a case for it here in Australia - Like Left foot braking modification - APR did that specifically for the Australian clients that take their MKIV R32's on the track - with the 80 + R32's we have done, we convinced them it was a worthwhile exercise

Your not going to get much more power unless you do hardware changes then change software to suit . You need to get more air into the combustion chamber to gain more power , its as easy as that , fueling can be changed a lot more simply by raising fuel pressure or putting in bigger injectors (once you get close to 100% duty cylce)

I'll disagree with Guy on the stand alone statement . The factory ECU is more powerful than the stand alone units available at the moment , in the mk4 r32 anyway . I would only go stand alone over factory ecu for a purpose built race car , even if its registered and driven on the street .

Interesting.....$s for bigger injectors?
$ for throttle boddies?

Yeah my thoughts for the distant future include things such as VF Stage II supercharger and cams. Haven't fully investigated it yet as that's something for later but if will of course be looking to see if things such as bigger injectors a DSG MAF etc would add to this as well.
I figure now is as good time as ever to start asking questions as of course the software is going to be needed.
Time and dollars... That's all I need...

Treza...iam right behind you on that quote....But i will stay with N/a for a while which i believe theres more in these motors to experiment with.

Race fuel
throttle body
?? Ecu
Breathing
Injectors

Just an FYI with this one that I cant see has been mentioned. Remap got rid of the flat spot around 3000rpm and also ups the rev limit

[Mr. JLT]

I have the Giac X program in my R along with a Cai and custom 3" exhaust and light weight pullies and i have been pretty happy with the set up so far. But i am looking forward to the new software soon.(unitronic)

How are you getting the Unitronic installed Mr.JLT? Have they agents over here or will you ship the ECU to them?

I got another Ecu for my R32 loaded with Uni software for when i start the turbo build. It was in the states already just had to get it shipped here with some other turbo bits
