Evening all,
Im in aid of some advice with my car
Back in June I had a full k04 conversion,cambelt,helix organic clutch,valve clean,runner flap delete, also I was running Revo stage 2+ then went on to Revo stage "3
this is the main issue Is what I'm dealing with, when Im on full boost it spiked@23psi then it backs off between 5500-6000k to 15psi then surged back up to 20psi and holds to red line
I thought that's not right so I phoned up I asked the question is this right, he said it's most likely to be the settings it's on to cause that issue, so I thought okay I'll pop up and have The settings looked at, he had the car 5 days he Phoned me up to say the car was running dangerously lean and the ecu is backing off the boost to protect the engine, the measuring block 001 was showing 24.6 enrichment on the lambda +25% is the max... so it was maxing out !
Am I right in saying when mapping a car your meant to look into these things to make sure it's running perfectly so they've either not bothered looking in to this when I first had all the work done or did and left it as it is and let me take it home on 2 separate occasions with this serious fault!!
Any advice would be helpful were I stand thank you
So just to depict it more clearly:
You had a regular GTI, you took them a box of K04 & other bits, they fitted it all for you, they flashed the ECU with Revo Stage 3 and sent you on your way?
Which parts from your list were already fitted prior to the K04 upgrade, and does this garage have a dyno?
I'm just trying to pin down the error point. Engines which have had a lot of parts put on at once can be tricky to fault find back to the offending part(s). I'm pretty sure something mechanical is amiss. It's highly unlikely the ECU programming is at fault. We just need to try and work it back.
The only thing my gut is tingling about is the aftermarket LPFP. Do you have the OEM one you could try, just to outrule it? Edition 30s don't need LPFP upgrades until way past 350hp, so not entirely sure what led you down that path?
