Log block 114 and 230 and all should become clear.

All dependant on engine load i'd imagine.

Id imagine like all previous logging runs, he'll be at WOT from very low revs to the redline.  If hes on the same stretch of road id expect the load to be pretty similar.

Load (requested and actual) often has no relation to throttle angle, load is the final request the ecu makes after taking all factors into account so if intake temp is high/low or ign advance is overadvanced etc... Then load value will change accordingly.

I'm used to all the other maps I had where it requested either 110, 121 or 130bar when car is under load, seems strange this new one does away with that, and actually modulates fuel pressure, which can only be a good thing at the end of the day.
Which is the best block for measuring intake temps?

+1 I cant really see anything bad from this.  Never seen it on any other car though.

004-4 iirc for IATs

I bought my autotech second hand. I have now nearly 80k on it with no problems. It gave a healthy 324bhp on JKM's rollers too.

Well I logged blocks 114 and 230, still isnt becoming very clear Dave, :stupid:
Its requesting full load, but now only 119.8 bar of rail pressure requested :confused:

Also the APR pump only provides 125 bar not the 130 bar fuel pressure that most software such as Revo demands on stg2+.


Sorry Dave thats wrong.

I've got logs of my Car on Stage 2+ with the APR Pump and it quite happily meets the requested 130bar.


Sorry, my mistake. I was going off logs from 2 cars with APR pumps and software, its the software that requests 125bar, not the capability of the pump.


....So am I right in thinking that Revo Stage2 (not 2+) on a K03 requests a max of 125bar and so the APR HPFP still has plenty of 'headroom'? And that it isn't necessary to upgrade to Revo2+ just because of having an APR HPFP?

You can run an uprated pump with any software Robin even stock.

Logging at JKM yesterday has shown that my stock fuel pump was struggling occasionally even with my boost turned down a notch on Revo2 to compensate for the extra air delivery from my Forge Twintake. So I've had to put my money where my mouth has always been regarding the HPFP subject. This has allowed my Revo boost setting to return back up to how it was.

Robin,
This is typical with Forge Twintake as it's so efficient it delivers too much air sort to say..... My tuner had similar issue when I got K04 on my gti so he had to tweak the map to compensate for it

Which one have you gone for RR, or have i missed it?  :party:

Over the top mod list ;o)
