The object is to cool the combustion chamber. The best setups out there are direct port, more even cylinder distribution and more consistent results. Water/methanol is used differently on diesel engines then in petrol engines.
Water meth - pd gains?
- Thread starter rod the sod
- Start date
Was indeed 3rd time lucky!
New controller wired in and all working perfectly.
Will now try and get it rolling roaded this week, if not it have to wait a couple of weeks.
Also thinking about adding a pre-turbo nozzle too
Just like to say thanks to Bruce @ methanol-injection uk for his help and speedy response in supplying replacement controllers.
Will be very interested in the rolling road results and the temp decreases!
keep me informed!
Well I can do a log on the temp decreases with vagcom.
Hopefully got a RR booked in either tomorrow or Thurs.

Well I had it rolling roaded today, with and without wmi.
It made no difference at all on a remaped pd130 tdi.
On the road, it feels slightly better and vagcom confirms slightly cooler inlet with wmi on. But need to do some more logs first to confirm.
I think it will help more in the summer, and will prob use almost 100% water.

that has surpised me! thought you would have at least had a bhp increase with a strong mixture on w-m!
as devon mikey boy said it may b more difference with a hybrid diesel!

I was disappointed but there you go. And was on a rolling road I've used many a time before (1st time over 16 years ago!).
It was an almost 50/50 mix too. I had it come in at max at 21 psi.
I tried reducing this to 15 psi when it came in full, but the engine over boosted and it was like a rev-limiter cut in!
I really need to do some proper logs when its warm outside. See if it at least has a cooling effect.
There are more gains to be had with a hybrid or bigger turbo car.
I think you need to get the map done to suit the added meth/water. A lot of the petrol boys dont get much gain until they advance the timing further to take advantage of the extra bang.
Water/methanol is used to solve the problem of excessive cylinder temps, EGT temp and to help keep the inlet manifold and inlet temps down. Unless your engine has been heavily modified or you want it to run for hundreds of hours none stop you are not going to get these problems. If you don`t have the problems water/methanol isn`t going to do much to your engine. If you don`t have the problem you cannot fix it.
Hmmm, thought about a custom map, not sure if I will or not. The water/meth is injected before the MAP and IAT sensor, so was hoping it would pick up on the cooler inlet air.
Well it probably will. Come the summer months when temperatures really do kick in you will notice you car feels fresher as you put your footdown and the watermeth kicks in. During those periods thats where you really gain power where the car typically would had suffered. I would go for a custom map definitely and make the most of the setup.
I am not personally attacking you or your car so no offence is intended but ....
What where you actually hoping would happen by fitting a water/meth kit to your car ? Please don`t just say more power as i could fit a hair dryer to my car to hopefully make it accelerate faster. Tuning cars isn`t that simple.
A ) I think you are trying to do diesel tuning while using petrol tuning methods.
B ) You are also trying to run before you are walking. Your car is only remapped. Water/meth is the new "in thing" at the moment for diesel tuning for some reason. Your car doesn`t want it or need it. Concentrate on the basics of tuning the engine ie FMIC,hybrid turbo,uprated injectors,ported head etc before worring about the fancy and what could be very damaging stuff.

Water methanol doesn`t help diesel to combust. It burns at a different rate,at a different tempature and ignites at a different compression then diesel. Sorry but why the hell are you messing with water/methanol to cool inlet temps when you haven`t even fitted a FMIC yet? A FMIC would be cheaper to fit,could never cause any damage to your engine, never needs to be topped up with liquid and works for free !
I did alot of research but maybe the sales talk persuaded me...
Its not the first car I've ever tuned. I know how hard (and expensive) it is to eek more power out of either petrol or diesel engines. Perhaps I was just trying to be different.
If helps prevent something else from making the mistake then something good has come out of it. I can always sell the kit on.

Well, the story doesn't end there!
I recently found I had a totally blocked jet.
So, I don't think it was working 100% when I had it rolling roaded.
Jet is now cleared, and spraying correctly.
So a few more tests needed before I bin the system!
