[928uk] 928 EPROM/ LH Jetronic

[Kingsley Sawyers, e-DBA Team]

Hi John

Pardon my ignorance, but is the EPROM part of the Jetronic brain, or does it
live somewhere else?

If the LH Jetronic unit dies, are you able to repair it, or do we all rely
on the nice people at Porsche to sell us a replacement?

That is really good news and is definitely the "best way to go" so long as
each EPROM is "set up" and blown for each individual car before installing
in the ECU and is not just provided as an off-the-shelf item.  Obviously
there are too many variables from car to car to make things like
"Superchips" automatically do what the manufactures say they'll do. In fact
sometimes they make matters worse.

I always think 'you' may have spent hundreds of pounds on one modification
or another and gained just a couple of bhp but the car might drive totally
differently.  My messing around did cost hundreds and gained me just 20 bhp
on the claimed factory output.....but the "straightening out" of the 928's
flat-spot transforms the way it drives



Hi David,
Well the tool will allow people to do "one off" tuning per car. The main
advantage is that once the EPROM is optimised, you can plug it in, and the
car is otherwise standard as far as wiring, hardware etc.

With some work, we have overcome issues in the Bosch/Porsche software, and
are assisting some guys in the USA with re-mapping the fuelling on their
supercharged cars.

I agree that improved drivablility makes a huge difference to driving
pleasure ! Worth the money !

John
