Updates.
Trip to Efi yesterday. Weather turned to shite early hours of Thurs morning typically.
Baltic -3deg
As the snow rarely lays in Redcar, was expecting a bit on the roads and slow driving so set off 11am as had to be at Efi for 3.30pm.
Full tank of tesco 99
Set off and 5 miles down the road passing Middlesbrough - no snow at all. Nothing all journey even m62 was decent so arrive an hr early.
Waiting for slot
Chris gets the meg strapped on the dyno.
Ready for action
Chris runs it up on old map and it pulls 263/290 which is better than expected. Chris then tells me that he thinks the clutch slipped a bit on first run so i might have some work to do. Heart sunk at this moment to be fair as was not expecting this as its never slipped on the road.
Not bad
Noted N75 duty was maxed out in the mid range so added more preload to the actuator.
Chris loaded up software and done the initial calibration. On first decent power run i noted a bit of wheelspin/tyre smoke. Chris said the slip he had observed on first run was actually wheespin and he had kept his foot in when it broke traction and it hooked up. Unsure if bit of s**t on the dyno rollers or tyres? After that heat cycle in tyres no issues so no expensive clutch job needed.
Rest of the tuning went well and done exactly as was expected. Seen 280hp on a few runs settling down to 273hp/298ft/lb.
Red overlay over original map.
Boost curve in red. So much better than the previous map in black which had all the boost low down falling off to nothing.
Quick test drive after tuning to confirm all good. Ready to set off home and it started snowing heavy! Had visions of getting stuck on the m62, but luckily nothing as soon as we got over the merseyflow so steady drive home.
Overall good improvements and fuelling is now optimal and boost control set up correctly.
Throttle response is superb. Previous map was opening throttle butterfly 100% at 40% throttle position to make it feel fast with loads of boost coming in hard, and resulted in loads of wheelspin. Now you can control the throttle far better its much more progressive.
Feels pretty quick on the road for a basic state of tune, with poor road conditions it hooks up great in 3rd gear and mpg is good noted 39mpg on the way back with steady driving. That will do me.
Thanks for reading!!
