injectors and remap

[Matthewj]

i've got some 0.216 injectors coming soon for my TDI the ones that are in the T5 151 bhp VW have you had any issue with remapping with these in ? got my clutch all ready done to take more power so just need to put these in and drive it down to you for a remap. Last thing would this be classed as a £150 remap or would it be a lot more as it's different injectors ? as I want it done soon after i put them in so need to sort some money out :) Also i take it your remap would sort out the VAG COM stuff like the EGR being change so there is less Exhaust recirculated and more fresh air used? and the ideal injection quantity or would i need to do this before ?

What is your engine output stock? What else is changed on the car with hardware? I can partially of totally turn off the EGR mixture in the software.
Dependant on the changes and what you want to do it would be slightly more in cost, the new clutch will help me wind it right up, so loads of torque! :)

its going from just the stock engine TDI 90BHP and the stock injectors 0.184mm. i will get a new intercooler at some point but not just yet. But it should be ok to drive till i get it to you shouldn't it ? my car is a 2002 if that helps as don't know the engine code. also it's a LUK DMF clutch in it they say it can take 250 ft-lbs << hope that good enough >>

[John@DNA]

Who advised you to go with those injectors?

yours won't be a 90bhp engine on an 02 plate. They're 100ps.


The 90bhp engines were import only. Unless it is a LHD import?

Will those injectors work ok? I know on late Fords you need to get the injectors coded to the ECU, will you need to do that on yours, or are they just Plugnplay?

[Matthewj]

oh well it may be a 100bhp one then it's not an import it's a standard TDI RHD. It's just a common mod to do on this engine to go for the T5 injectors some people i know with it run them on there Mk4 golfs without a remap but they run smokey.

[John@DNA]

It's just a cheap way of adding fuel, you don't need to do it if you're changing the software as you'll never reach the maximum duty cycle unless you go to a hybrid turbo!

[Matthewj]

oh so having these injectors in will not give me an advantage over the stock ones when i come to remap it with you ? I thought the injectors where one of the limiting factors when your tuning. ofcourse it's the turbo and an intercooler after that as well. I was getting a lot of my info from www.tdiclub.com (http://www.tdiclub.com) and there FAQ bit http://www.tdiclub.com/TDIFAQ/TDiFAQ-6.html#e3

[John@DNA]

When you start getting into non generic remapping then it opens it all up, they only discuss a couple of US stage 1 remaps being used, I do all the work on hybrid conversions int he software so the clutch is usually the limiting factor :)

[Matthewj]

oh well got them coming in a day or so now :) so in a month or that when i manage to get to you we can see how good my LUK clutch was i did want a VR6 clutch and G60 flywheel but time was a factor as needed it the clutch in a week so had to stick with DMF (dam heavy lump) clutch. but that is the best i could get so should hold up to a fair bit of mapping.

[John@DNA]

Do you know your ECU number? I can check your std output

[Matthewj]

nope but how can i find this out connect to VAG COM ? as i can look tonight.

[John@DNA]

VAG-COM and log into address 1 Engine, take a screen grab if you're unsure which info to send us :)

[Matthewj]

ok cheers will post it in this thread later tonight then :)

[Matthewj]

ok i'm pretty sure this is what you are after :)

Yeah that's the 100 bhp version :)

Doesn't sound like it would make a difference, but the 90bhp engine is a completely different engine. The 100 and 105 are PD engines, where the 90 isn't.

[1958 Harry]

PD Diesel engines are basically Common Rail injection, whereas the earlier engines are Direct injection units :) I think the actual engine blocks are similar its just the injection system thats changed :)

Pd's aren't common rail, they are essentially injector "pumps" that pump fuel at a higher pressure creating higher atomised fuel, thus increasing economy

Common Rail on the other hand uses a high pressure fuel rail feeding solonoid valves as opposed to seperate pumped injectors as on a PD

Much cheaper to do, hence why VW have dropped PD engines now in favour of common rail in the mk5's onwards

Carry on :)
