chips for b-20 - Diesel Forum

anyone here think we need to retard injection timing while running b-20?because of the high cetane rating of b20 or b100.

Acually, if you could get a custom chip burned for the purpose of retarding the injection to run on B50+?, I would imagine it to be a good thing.

Can the timing be retarded on a PSD via chippage?

Mannytranny did you get the water pump fixed on your Volvo?

No. I cannot find anyone to do it.

If I want it fixed, I will have to rent a trailer, and take it ~50 miles away.

I will probably get it fixed within a few months though. Its just with these diesel prices, the TDI is the best car to drive. All I really ever used that car for was a short trip replacement driver for the TDI.

IIRC, It got somewhere around 28 mpg.

I would fix it myself, but the waterpump is off of the timing belt, and I dont do timing belts on interferance engines........

Ill get around to it someday............

The main reason for retarding timing is to reduce the Nox emissions of B-100. I personally wouldn't bother messing with the timing until getting to B-50 on a regular basis.

As to the chip being able to do it ?????. Might check upstairs in the appropriate fourm for your engines perfomance mods, or the general questions?
