Hmm, I was running rotitional idle and anti lag on my little GTti.

Rotational idle was used to spool up the turbo on a standing start. >12psi from the word go! (Then it would hit 26psi @ 5,500rpm)

Anti lag was used between gear changes to keep the rather large hybrid turbo spinning.

I would use the rotitional idle as a crude form of launch control. The MoTeC M4 Pro was set to cut the coil packs, but still allow fuel to pass through.

While staging, you would hit the launch control button on the steering wheel, engage 2nd (Never first gear) clutch in, and foot flat to the floor on the loud peddle.

The MoTeC would hold the revs around the 5,000 rpm mark, but keep on cutting the spark to the cylinders at random. While the throttle was wide open, the resulting pulsing from the engine would cause the turbo to spool while you are standing still.

As soon as the clutch engaged (A micro switch on the clutch peddle) the MoTeC would then switch off rotitional idle and run the proper maps. (IE: 9,500rpm cut, and anti lag turned on)

I used rotitional idle to gain boost while standing still.

Worked VERY well, but produced 6 foot flames out the back. (Cat died a long time ago)

Had a 5-8 second window of using rotational idle, over that, everything started to heat up badly.

Anti lag 'can' be used to get the turbo to spool up before launching, but is a very crude form of doing this, since you have to rev the engine right up, then lift off the loud peddle to get the antilag to kick in.

At least with rotitional idle, I had the throttle wide open all the time!

Boy am i glad for google or i would never have looked here!

Hi dragon, my name is clay and i have recently bought a GTti.

I have been searching for someone that can tell me how to get great performance out of this little car and it looks as if i have found him.

I rang MRT but they were very unhelpfull as they dont do charade's anymore,,,,their suggestion was to buy WRX!

I also tried the daihatsu charade site but all they wanted to do was to bag me out about my job and my spelling!

Bunch of @#$%^&!!!

Still all is good now because i found this site and you!

Can you please fill me in on how you built that weapon of your's and what sort of power it was capable of?

Help me obi-wan.....your my only hope!

I can only assume you haven't answered me because this was lost in a thread so i posted a new one so you can hopefully help me out as you have helped so many other's!

:(

Thank's for this dragon! :)

Clay.

Oh come on... we give almost every newbie at roasting at the Charade board.

You're lucky to have found Dragon though, his G100 was an absolute ball-tearer, I've got videos of it doing a hillclimb, I'll email them to you, amazingly quick car!

If anyone in Australia knows how to get one of those Charades to move, it's Dragon! (well, Neil Trama had a hand aswell, but I think Dragon did a fair bit to it himself)

Was a very cool car too, I sat in it when I was in Brissie (unfortunately the gearbox, or was it the diff? was broken at the time :()

Cheers
