Engine Remap On Auto C8

[Wirdip]

Hi guys, have managed to sort previous electrical problems and have had auto box serviced and oil changed. I have found from service history that the engine was replaced by Citroen at 78000 and car has done 103000 so engine is in good nick. Mpg is not that good and car seems slightly sluggish so was thinking of remap. Has anyone any advice or experience of doing this with auto box. Was thinking of stage one from HDI tuning which gives 145 bhp. This is less than 2.2hdi, does this use same (al4) auto box.

Any thoughts or advice appreciated.

Yes, it is the AL4, I don't think this is the reason, however. Replace the Diesel filter, Check and clean the MAF sensor (avoid touching its inner components) and the Regenerate your FAP, before going into expensive stuff.

I had a power problem with my car, I tried every thing and having a Lexia tool did not help. At the end it was CAM (timing) belt, it was off by one notch and there was a very tiny hole on the inlet manifold butterfly vacuum adjuster plastic body as result of a hose friction against it, causing air leak and resulting in a different mixture from that controlled by the ECU (I have written about it in this forum).

 

Please be kind enough to reply as to benefit other Citroen owners.

Hi Simple, thanks for quick reply, car has just had all filters changed but will get cam timing and maf tested next week also turbo boost pressure and then repost.

To check the cam timing you will need to remove the timing belt covers which could be almost as much work as replacing the timing belt. So if the belt has not been changed recently and you are paying somebody to do the work, I would also consider replacing it. If you do replace it then the pulleys and water pump should be replaced.
