I thought that I should update this, as I was pretty vague with my last post on here.
I had an increase of torque, which helped at lower revs, but there was no more power. The remap had claims of up to 125bhp, but it was nowhere near that, which I why I said the jury was still out.
Using Cruise Control started causing antipollution faults and limp mode being activated.
Shutting the engine of for a couple of mins cleared the engine management lite and fault, but again, it came back with CC.
I found out at the weekend, that the ECU I bought to send to HDiTuning for the remap was different to my original. I did not check any numbers. I just bought a SID801 ECU as I was under the impression that an ECU was an ECU, and as long as it was the same base make (Siemens SID801) it would work.
I emailed Vinny at HDiTuning on Monday about it, telling him I found out that the ECU was wrong. He said that it could not be wrong, or the car would not run. He asked for, so I sent pictures of my original, and the one that he mapped. He replied with incredulity saying that it was in fact totally wrong inside and out (the tray that holds the ECU in the car had to be cut to get the mapped ECU in) and that he was surprised that car ran.
We arranged for me to send my original ECU in for him to work his magic on, and I got it back today.
My initial reaction as soon as I pulled off was "HOL FU*K!
The car is now rapid. No hesitation, just put the accelerator down, and there is instant response, and it pulls pulls pulls all through the rev range. It is transformed my car. I am at a loss what words to use to explain how quick it is.
I am only talking comparatively of course. Compared to a Focus ST or Polestar Volvo, it is still a slow old diesel. However, comparing the standard 90bhp to what I have no is like night and day. I had no fricken idea it would be such a vast increase in power. I would ALMOST call it a hot hatch now it is that good.
I have only been for a short drive, but I got to know how much harder it accelerates, and doing 30 in 4th, I am getting 15 mpg more with a cold engine.
I will have to see what MPG is like over time and distance, but it looks very promising.
I will also have to see if the Cruise Control issue is resolved as well, but I am pretty confident that it will be.
If any of you are thinking about getting it done, it will be the single best £165 you could spend on your car. I got an EGR delete and Immobilizer delete as well, which cost a bit more. I cannot stress enough how good it is.
Get it done, you WILL NOT be disappointed and WILL NOT regret it.
I have no connection with HDiTuning other than being someone who has made use of their remapping service.
