Had my van retuned after getting the PP2 fitted, but ideally I would like to know the nozzle size for a better remap. Anyone know the nozzle size of rakes pp2 injectors.

My remapper needs the nozzle size to be able to adjust the fuelling correctly, my remapper rung rake and he wasnt for telling him, cant understand why I cant get the info from him, the only other way my remapper has said is to pull one out and measure it. Whats the big secret. The remap cant be tweaked until he has the nozzle size and is still running rough, surely if you are selling a product it would be nice to have the info needed also

True, I mean at least all U that have bought them should be told.
A polite reply to us that havn`t would be the very least. If I would search high&low I would probably find a figure I:
Pulling them is off couse an option but completely unnessesary :*

Hope he at least comes through on U`r end mate, this is not very satisfying!!!!

Completly agree, I didnt take mine to the recomended remappers like chipwizard or pendle ,they must know the nozzle sizes as they do quite a lot of pp1 and pp2. But took mine elsewhere. The remapper said he refused to tell him the nozzle size even after being told he would struggle to do the remap correctly. What gives its only a nozzle for gods sake :* It would be nice to know what you are actually paying for. If you are reading this Rake can you tell me the sizes so I can get my remap sorted once and for all

tell your remapped to live emulate vehicle and tune in real time, he can then in real time correctly scale the pump voltage map.

Reason your mapper wants nozzle size is that he simple hopes to find what vehicle the nozzles are fitting in then copy paste the pump voltage map of the software that the injectors are fitted in into your software - honestly this will not work.

To correctly scale the pump voltage map to suit different size injectors takes time and setting up in real time making adjustments in real time until you have the complete map scaled.

In this image below you have the Pump voltage Map (Duration Scale map) The axis are Engine Speed (RPM) vs Injection Quantity (mg/Hub) and the map itself is (mV)

Honestly copy pasting a pump voltage map from another software simply will not work and will probably make things much much worse, the only way to do it is to correctly calculate and scale in real time tuning which takes time and skill (sorry but true)



Hope this helps a little.

Thanks for posting Martin, it was nice to get a different approach to this T:
Regardless of this the fact that a certain company will not disclose the nozzle size (output) is not so satisfying even when comparing products & where to potentially leave U`r money.
Some are more equal than others?:*

I agree when you are buying something you should have all the info, If I had the info on the injectors I would happy share it with everyone.

It's been quoted countless times on here, I think it's .261 but have a search.

The reason Ron (Rake) isnt bothering to tell you is that any decent tuner/remapper doesn't need this info. Live mapping is the way to go, not cowboy generic stuff.

You are right, when I had mine remapped a couple of weeks ago he pulled the old map off the van which was done by a respected, well known remapper a couple of years ago to find it was off another T4 with a different reg no to mine, I would call that a generic map

The software within these VW T4 2.5TDI engine control units do not store reg numbers or anything else like that, also the software in there would have to be the correct software for the engine control unit with the correct checksum calculated for that software or the vehicle wouldn't start.

Again being totally honest any mapper saying anything at all like this really hasn't a clue what they are talking about and usually just making things up to look good in front of customers (sorry I'm only being honest here with this answer)

A Generic map in my eyes is when a tuner does something like 20% Drivers request / 20% torque Limiter / 20% Smoke Limiter / 15% Turbomap etc etc... and they do this in every software version they write for each and every vehicle they tune.

Oh man, what can you do? My brother used to own a diesel tuning company, made an awful lot of money but also found generic maps, or maps created over the phone with a few 'requirements' listed could cause all sorts of problems like repeated clutch failures, even on the same day they were fitted, including Kevlar and ceramic!

Just go to one of the reputable live tuners and enjoy the results. I did and I can't stop :)
