Title: Power delivery
Post by: ruhaleali on January 10, 2015, 01:19:39 am

Do a lot of you guys get spin with traction both on and off. At stage 1 with 316 torque.

I'm stage 1 and can spin in 1st, 2nd and 3rd. However, the previous map I had was worse as there was a massive boost spike which always broke traction. The great thing about the Rtech map is that you can adjust the power with your right foot so can still get away quickly with little/no wheel spin.

I think I need to upgrade my tyres though. Was thinking some pilot sports.

I'm at 314bhp and 320lb/ft.

Niki has mapped the traction control to just pulse the power in & out rather than kill all the power, works really well.  :jumping:

I can use full power at top of second gear in the dry, and basically use all of 3rd even in the wet without wheelspin  :surprised:

I have Michelin Pilot Supersports and they are just  fantastic. No other tyres I've tried come close

I 100% agree with you regarding the Supersports......they're simply fantastic tyres! :grin:

I am very interested reading about the TC mapping that you say Niki has done for you as it sounds like a great idea. Mine is in next month and I'm hoping I get all these gucci options on my map too, does he include them as standard or do you have to ask for them? :party: :innocent:

Was good to meet you down at AKS the other month, glad Alex sorted your clutch issie out so quickly for you too! :happy2:

Yeah my mate Jairm's got the same
sounds like anti lag on the TC instead of it cutting aggressively it sort of pitter patters very weird but swag

Does the TC / ESP use the brakes much, as I though it did or is it mostly ignition cut?

Think it's igntion cut. Not 100% sure though

The ASR cut times are raised to match the ramp rate of the cars power.  Most will miss the ASR mapping and leave it stock which is factory calibrated to the cars stock power output.   We tune it so you can have as much power as you can get down on the road on but the ecu cutting the power back to the edge of wheel spin point.    The asr light flashes fast the ecu used timing torque reduction via missed timing intervals or opposing timing phase depending on load / rpm to stop the tyes lighting up.   So instead of the stock sudden cut of power when the tyres slip which jolts the driver forward the car will now still accelerate with the cut recovery back to power up to 50 time faster than the factory settings.   

Plus most of the time (depending on customers demands and stage of tune) I aim for flat linear boost tuning by progressing the n75 duty with rpm instead of spooling with 95% n75 to give a spike and recovery control boost profile.
