Hi All,
Rather than hijack another thread, I thought best to start fresh here, as I know I am not alone in this issue.
I had a Pendle remap done by Outlaw Tuning in Wigan area, the guy was quite thorough. Scans/logs prior and after. Job done, about 3 hours.
I drove it with the agent in passenger seat, and, it drove great. Power increase was fantastic. And, still is.
Later that night, I had to collect the kids. And, I drove very light footed, as you would being sensible.
There was a noted power fluctuation.
Not a specific miss, but feels like boost can't make up its mind. It's pulling, then holding back.
At 20 percent and over throttle, beautiful. Pulls like a train. Zero misses or holding back.
10 to 15 percent throttle. 1500 to 3000 rpm, the feeling is best described as someone pulling the handbrake gently on and off.
This happens from 10 to 70 mph at light throttle.
I called the agent "Outlaw Tuning" that same night, and he promised to ask Pendle HQ what to do next.
I have called/texted since, and told it would be looked into.
No issues prior to remap.
Outlaw makes logs on stock van before even applying maps, these are sent to Pendle HQ for checking before work started.
60k miles on van.
Zero misfires recorded during the occurrences, which is EVERY time its driven.
Fuels tested - Regular and Super unleaded.
To remedy, I have tried the following:-
Bosch Coils and plugs.
Milltek boxed system - Cat back (I had this to fit already)
Forge recirculating valve on turbo - Made power much better, and actually caused the clutch to slip.
I had a Helix clutch and DMF fitted as slipping occurred after valve
All scans show no faults. No misfire counts. (via Carista - limited I know)
Stationary scans show zero faults in ANY system (VAGCOM)
I need some better weather and assistance to log the parameters with the laptop.
My gut says the timing is being pulled back in off boost light driving, the exhaust note changes a touch like retarding.
Maybe logging RPM v BOOST, and RPM v IGNITION etc.
The agent Outlaw Tuning has still not responded, and I am far from impressed. I went with the Pendle system as prior reading/research shows they are one of leading, along with REVO for these platforms.
I do not mind spending coin to fix things, but, I cannot aimlessly throw funds at an van with no assistance. I am not blaming the software either... YET.
Just to be clear, I will exhaust every avenue to try and rectify this, as it could be an out of spec sensor, or sticky valve. (the forge recirculation made a great difference to mid/top end).
As some history, I have extensive experience in standalone ECUs, and applying maps to cars written by software companies. Around 5 years worth. I know the way things work. I know the VAG can be funny with sensors/valves on certain maps. I have reflashed Fiesta's to Ferrari 612's back in the day. I have also had to fix sensors where they are out of spec, and cause maps to exaggerate problems (common on the golf 1.8t/Audi 1.8t etc.)
I will update and post some data here when I get onto it.
