Hey Vanne,

I got the tune straight from evolve uk. It is a "stage 2" decat and all torque limiters removed tune. Like I said haven't had it on the hub dyno yet but the BUTT dyno feels good.

As a matter of interest I'm gonna be in dubai for a week, are you ex South African? Lekker?????

So it's been a while and after hopefully my last NA track event a big push to get SC sorted resulted in some good progress.

I'll attach some pics later on... Reading bad... Pictures good...

Boost pipes sorted, cooler mounted, bracket and sc fitted. I modded the tensioner to solid and also added an additional idler/tensioner pulley just below the charger pulley to increase wrap around the pulley.

Power steering bottle moved, still need to do some plumbing. Still need to wire up the air temp sensor and finish my breather bottle and sump return.

On a positive note looks like we have a solution for tuning, gonna use an EVOLVE ALPHA N base map to get rid of the MAF, then we gonna use a UNICHIP Q to look after timing and then UNICHIP I DRIVER with a Dastek MAP input thingy to run the injectors. The idea being we can live tune and then drive/tune the injectors completely separately from the DME using a MAP reference so that altitude and a change in boost won't necessarily need a retune.

Lets hope it all works out

Not actually 100% sure at my altitude of 5000ft but I'm starting with a 3.15in charger pulley if I'm not mistaken 5.3in crank pulley should give approx 10 psi at sea level so around 7 psi at my altitude???

Perhaps you gents can advise?

Sadly missed you in DXB, a chat would have been cool man, and you could have talked me through that oil cooler install. Looking possibly to do the same, the weather over here is soooo hot.

where did you source the coolers from? any more pics of the cooler install?

hope your going well mate

please update on the unichip, that sounds very, very interesting
