Just a little, although the video pick it up way louder that it was. It hasn't been fired up for about a year or so though :D :oops:

After hunting down and fixing a fair few problems with ancillaries, finally managed to have a play with the fun stuff, like launch control....

Looks like a lot of fun. Presumably a lot of weight out back ? How does that handle ?

At the moment it's understeer city, but I think it's mainly the plate diff being too snatchy and the front arb is harder than ideal (I originally set the sizing based on an open diff for traction) - it doesn't help it has steering brakes and the diff overwhelms them at the moment too.
Usually it's not too bad really apart from struggling a bit on side slopes.

Gonna rewire the VTEC over winter I think off the AUX5 12v output and onto a solid state relay instead - it works fine but trying to fine tune the fuelling around the switchover point without having the enrichment on switching that's available using AUX3 with VTEC/MAP2 settings is a bit of a pain, always end up with a flat spot beforehand to compensate, especially when running some hysteresis so it's not flicking the VTEC on and off rapidly when the wheels are skipping around.
Also having the 2nd MAP for VTEC lets me shift the engagement point around a lot easier for places where the car drops right on it on a gearchange, I can just shuffle it out of the way one way or the other without touching the fuel or ignition maps.

The one thing I'm not sure on there is does the input hysterisis on AUX3 work when it's in use in it's alternate function as a VTEC control?
I really wouldn't want to have the solonoid getting flicked on and off 5-10 times per engagement as the RPM's spike up and down a few hundred revs around the engagement point as the wheels are scrabbling for traction...

Fine to be honest, little soft on the compression and it needs a little work on the rear kickup but I did quite a bit on that through the season, and I'm going to change the valve stacks this winter, get it off the flutter stacks in the rear compression side that those come with stock - it robs too much mid speed control.

If you used MAP as load would it overcome the issues of when the vtec switches?
