ECU and Accelerator interception and enhancement...
I jumped onto the Chipit group buy a while back. I was tossing up between either a chip or ECU retune for a long time. I read every post, review and comment about both. Both have there positives and negatives though for my application the Chip was the easiest option.
I not after huge power I just want to get back what I've lost through the extra weight, drag and larger rolling stock. I took advantage of the discount and bought the full kit with EGT, fuel limiter, OBD2 scan tool and Sdrive throttle controler.
The chip is a full 'plug n play' system. The harness is prefabed with all the matching plugs to allow for a 15min install. I took the time to ensure the loom was routed smoothly without any kinks. While everything was loose I gave all the plastic plugs a dose of silicon spray on the outside of the plasic connectors to keep them from going brittle.
The kit came with a billet blank for the fuel rail though I wasn't keen to use that on my setup so I exchanged it for the Hi Spec unit. This was one part of the instal that I wasn't too keen on to be honest. I'd had a couple looks at the location of the limiter and all the stuff in front and around that I put it in the too hard basket.
Tune 5 ran a dream and I was very happy with the result. I had a play and loaded Tune 6 then 7 though it seemed to have less power with a noticable flat spot around 3000rpm. I assumed that maybe the standard limiter may have been the cause. Armed with a fist full of tools I dove in and swaped over to the Hi Spec unit.
It was a easy job though there is a lot to remove and reinstall to make it happen. In a nutshell you have to remove the battery and tray, move the dipstick, disconnect the loom, remove the throttle body, remove the EGR pipe, remove loom support brackets then you've got enough room to get to the banjo bolt on the end of the limiter.
Once you've fot that off the line needs to be gently moved out of the way to enable the fitting of a 19mm spanner onto the limiter...
These things are dam tight though came loose with no spilled claret...
The upgraded unit fitted, done up tight enough to pop a grape out ya date then reinstall everything in reverse order. I took the time to clean the throttle body as there was a mist of oil residue. Re sealed the EGR and torqued all bolts back up to spec.
I went for a test run and Tune 6 went a lot better than had done previous. With no fuel leaks or issues I'll put this one down as a win.
