JustGav Posted May 24, 2009 Share Posted May 24, 2009 Anybody have any experience with tuning performance diesels? At the mo, I'm after articles and just some general info for research. Particularly the VW tdi engine... Had a bit of a search, but the two links I found were a little light. Quote Link to comment Share on other sites More sharing options...

Good call, I'll buzz Ryan a bit later.. the only thing i'm aware of with diesel tunning is just remaps. not sure on the power gain . I understand the simple theory, throw more air and more fuel and get more go , but just wondering on the quirks and intricacies of it. I'm not sure at all how the modern ECU's do diesel management, the old school ones were simply turn up the boost and wind up the pump, however I'm looking for something slightly more advanced Quote Link to comment Share on other sites More sharing options...

Kranz Posted May 25, 2009 Share Posted May 25, 2009 N plate 106 is probably quite easy to tune as long as it has a Bosch fuel pump Quote Link to comment Share on other sites More sharing options...
mrdsukautos Posted May 25, 2009 Share Posted May 25, 2009 Watch the heads on thos tdi engines they are well known for costly rebuilds If you havent already got the diesel car perhaps look for one thats had all this work done already Quote Link to comment Share on other sites More sharing options...
Paul Posted May 25, 2009 Share Posted May 25, 2009 I've fitted the power upgrade box to my L200 2.5 TD, Mitsubishi plug and play jobbie, fits inline by the ecu. The difference is very good, I guess it re-maps everything? Only thing is the engine sounds alot noisier, reading forums though this is normal?

If so they aren't quite as clever as you would think. Its normally a resistor that fudges the air flow reading. This in turn leans out the air fuel mix and gives a bit more bang for your buck and uses less fuel. It isn't a remap though. Quote Link to comment Share on other sites More sharing options...

It's the genuine Mitsubishi Ralliart one (Silver box), as sold by main dealers. I know the later model ones have to be fitted by a dealer but mine's a '55 plate so it's an half hour job. Are the genuine Mitsubishi ones the same then, a simple resistor? Quote Link to comment Share on other sites More sharing options...

I doubt the legit ones will be bud, sounds pretty good. If it was the ebay one it would be a warranty killer, i'm guessing the one you have is warranty safe?

Yeah, that's why I got it rather than the other type although it's now out of warranty it wasn't when I fitted it. Still a con though and they are doing the same with the new model, charging loads for an extra upgrade box so it drives OK. Almost seems like they de-tune it off the production line and then charge for getting it up to spec. Quote Link to comment Share on other sites More sharing options...

This is hopefully a possible project for the step daughter. Just weighing up the options of using a TDi lump, it would be fully rebuilt by her anyway.

If she is gonna rebuild top and bottom fully then as diesels go for a cheap option a tdi car would be best option when it comes to price and bang for buck Quote Link to comment Share on other sites More sharing options...

The caddy shells are cheap enough and she can spend the time on it. At the mo, it is just an option she is considering, might probably change, you know what kids are like.

RED_ROCKET Posted May 25, 2009 Share Posted May 25, 2009 ooh interesting ive got a honda frv diesel it has 150 bhp not to bad but a bit more would be nice Quote Link to comment Share on other sites More sharing options...

I did have it running on it last summer but then the price rocketed and became more expensive than diesel. Quote Link to comment Share on other sites More sharing options...

At the mo, it is just an option she is considering, might probably change, you know what kids are like. even better a caddy nice and light would go like shit off a shovel with 170-180 bhp tdi lump in it and yeh these youngsters nowadays they have the attention span of less than a goldfish lol edit - thinking about it she would give your supe a run for its money in 1st and a chunk of 2nd gear, maybe that would have her focus a bit more on this instead of wandering aimlessly like kids do XD Quote Link to comment Share on other sites More sharing options...
Kranz Posted May 26, 2009 Share Posted May 26, 2009 Are we talking running it on Veg oil? I did have it running on it last summer but then the price rocketed and became more expensive than diesel. No, just winding the fuel up a bit..... but as its non-turbo then its not much. Fitting the XUD9 (1.9 td lump oyt of the 306 etc) would be a good idea as that can be tuned to 130hp, and I have most of the parts to do it Quote Link to comment Share on other sites More sharing options...
lui Posted May 26, 2009 Share Posted May 26, 2009 Company called tunit are very good for external chip boxes one of the best around going to get one for my van see link below: been highly recommended from this company by a few people http://tunit.com/ Quote Link to comment Share on other sites More sharing options...
tDR Posted May 27, 2009 Share Posted May 27, 2009 Interested in this topic too as I've just ordered up an Alfa Romeo 159 Ti with the 2.4 JTDM lump (5-Cyl) as my new daily driver - getting it through Mangoletsi, an Alfa main dealer who offer dealer option fit Autodelta piggyback units for the JTDM engines. I'm told it takes it from 210bhp / ~295lb/ft torque to 250bhp / ~ 375lb/ft torque and won't invalidate my warranty... I was sold at that point! http://www.mangoletsi.com/content/i/Alfa%20159_Ti_04.JPG Anyone have more info on them? Do they just increase the pressure of the fuel system over the already high common rail pressures or are these piggybacks more sophisticated? Also, can the engines / clutch / gearbox / fuel system take such an increase happily? I *think* there are dip switches inside the unit whereby I can turn the wick up further if I dare from what limited info I can find on them, but not sure what effect this is having on mechanicals... Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
