Another Wreck, another Race Car.....

I'm not 100% sure what you did here, but making up a bespoke dizzy is badass

I'm old school (very old) and I notice there's no provision for mechanical advance/retard. Is this function available through your management system?

If so, is the advance curve fully programable?

Cheers

Yes, that's correct all ignition timing is done via the ECU.
This sensor only really tells the ECU which stroke no1 is on, compression or exhaust.

The main timing reference is a toothed wheel on the crankshaft.

The ECU has a lot of stuff it can do with ignition timing, the advance curve is just the beginning.

Launch control, traction control,rev limiting, idle, hot start, etc etc, all sorts of stuff.

You can even set it up for different advances per cylinder. Air cooled motors for example run No 3 cylinder slightly retarded to keep that cylinder a little cooler.

I'm running one coil per cylinder, they're fired sequentially. In production cars they're commonly fired in pairs on both the compression and exhaust strokes (Wasted Spark)

I could also have used a single coil and a distributor cap. The ECU can be programmed for all of those scenarios.

There's almost too many choices to be honest, it does my head in trying to figure out how settings interact with other settings.

Amazing build!!!
I read through most of the build and I got to post # 789 and saw you were using Redline shock proof oil. I recently installed a wavetrac in my 02J and I know you shouldn't use that oil. It doesn't work well with the friction plates and also I haven't had any success with that oil lasting in our endurance car. We have gone through 2 transmissions and it also seems to wreck the syncros. We have changed oils and haven't had a issue since.

Wow, thanks for that.

I tried and tried to get oil information on the Wavtrac oils and never got told that.

All I got was the factory fill information but nothing specifically about not using the shock proof oil.

Which oil do you use now? I'll change mine out before the next race after reading this.

Thanks again! Pete

I ended up using Motul 300 gear oil. I also like Liqui Moly 75w90 we have run both oils with no issues.

Back into again after a long break.

I missed a bunch of events due to work travel commitments, upgrades and repairs.

EuroSpec have been helping me out big time with ongoing development. The car goes on the dyno for tuning again after the Vic Day of The Volkswagen show next weekend.

I took the Golf out to Phillip Island yesterday to get back in the seat and test out some of the mods.

I've added an adjustable pressure limiting valve inline with the rear brakes and it seems to have helped with some of the high speed breaking instability I was experiencing.

There's been a few plumbing mods as well in the oil lines to make bleeding the dry sump system easier.

Quick connects have been fitted to the oil tank and sump to make the oil changes easier.

I made some new water fittings for the block to delete the steel pipe.

New Lambda sensor setup. Upgraded from the Bosch 4 wire sensor to an Innovate LC-2 system and integrated it into the DTA ECU.

Better USB power adapters for the cameras, GPS etc in the car.

I'm entered for the Geelong speed trials at the end of November. Geelong Revival | Brings Speed Trials Back to the Geelong Waterfront I'm not really geared for 1/4 mile, should be a bit of fun anyway.

Been a bit quiet on here because I'm spending a lot of time at the moment sorting out Amarok wiring for the folks over at the AusAmarok forum.

Here's some pics from PI this weekend.

Nice work, was wondering where you got to! Any PB's? Are you in the shed today?

[grandturismo]

Always great pics.
Not many folks run the Tarox brakes Pete, how are you finding them? Are you using the .116 pad?

[Peter Jones]

The Tarox brakes are awesome, yep I'm using the 116 track pads.
