S2 Avant MTM -> RS2 -> GT3071R -> CT355

[Bram]

Hey thanks for replying. VEMS does not use the MAF, so I don't run it.
Also IIRC VEMS uses the hall for the entire RPM range, but I am not 100% certain about that thought.

1. I still did not try to reflash VEMS to 1.1.27 using the old method (with paperclip method). Only tried going back to 1.1.27 using VEMStune and load my old config with Megatune.

2. Other options that could cause the problem might be a damaged injector. The MAP sensor and lambda seem to respond normally so doubt if they are causing the problem.

3. Another item I need to do is borrow a dual-channel scope to time up the hall window exactly with the trigger from the flywheel.

I have 2 weeks left to check those 3 items before I pull the engine and put it in the garage.

Well I hope you manage to fix it soon.

I have just PM'd Repo I am hoping to goto the Ring in September so hopefully if you are free and the car is running we can meet up on my way. I don't want to 'copy' your setup, but it seems pretty good!

Hey Bram, how are you getting on with the running issues?

I have a quick question, did you manage to keep the OE cruise control with the Wagner reverse IM?

[A80Avant]

i did!

[Bram]

I am not running Cruise Control, but I think it is possible. Ask Vas

Today did some measurement on the hall - VR reference pin signal.
At least I know that this seems to be OK as the VR signal falls in the hall window as seen on the scope.

The blue line is the hall window and the yellow sinusoidal wave is the ref signal

As I raise the throttle the yellow sinusoidal's amplitude increases and stays within the hall window. However still at 1500/1600 RPM the engine stalls.

The search continues.......

[Bram]

Well after spending a lot of hours searching for the issue of the 1500 RPM drop dead RPM.......

I decided to pull out the engine and look to it on a later date.

Today I finally managed to finish the OEM engine ABY transplant. Big thanks to Nero, Jaco and Bart76 for helping the swap of engine and components! Yesterday I also found a dodgy hall sensor cable, so that might have caused the RPM issues I was facing


Now it's only soldering the Motronic, put in chips and it can be driven again! Fingers crossed!

I got a real dejavu when I looked at this picture and saw that 5 years ago my engine bay looked the same

[quattrostyle]

good work, on to the next project

[Bart76]

No thanx Bram, I'm driving my avant with a big smile since I bought your exhaust..

hehe, the engine is running finally. Had to replace the trigger sensor on the FW and repair the Motronic ECU. So much time lost with solving this.......

Now preparing for MOT

[Billman]

The big hp is running or the old one?

[Bram]

The stock ABY engine off course. The high power engine is sitting on wood in my garage waiting for a new project. My Avant will go on sale very soon. I need to sort out some details before I am happy about it.

[Bram]

Had to get the dust off the car so went for a wash and while the sun was out took some pics of the Avant. I like the way the cobble stones reflect in the paint.

are you putting the brakes onto your next project or are the being sold with your avant?...

it seems a few avant owners are selling up...

The GT3 360mm Porkers will be sold with the Avant as well as the complete RS2 interior
