Title: TDI Performance. Diesel Power Modual added.
Post by: Eric18T on November 09, 2005, 09:02:19 PM
Below is a chart showing  before and immediatly after the addition of the TDi Power Module.  Once the car got going it accelerated much faster and you see in the below chart which was created from Vag-Com data logs that once the car hit about 2500rpms it took much less time to go up in RPM's vs before.

Tested in 3rd gear:

Prior to the module addtion it took the car 11.57 seconds to go from 1827 rpms to 4074 rpms.

After the additon of the module it took the car 10.08s seconds to go from 1848 rpms to 4074 rpms.

That is a difference of ~1.5 seconds for 3 gear to cover the same RPM range.  For a simple addition that went thru NO adaptation period that is great.

Here is the graph for your veiwing:

Purple is prior to TDi Module, Blue is after TDi Module

Can I try out that module for my Passat TDI I think my engine is about broken in enough :D

I am seriously thinking about getting one of those.  I would like to see the differance on a dyno.

You running stock exhaust and intake setup on your  TDI?

Josh -  Unfortunatly your car is the newer PD TDi. Our is the older TDi and they have a completly different fuel delivery system. Your PD will actually respond better to the module than my car, but the modules are NOT compatable. I have a dyno chart floating around somewhere of a 2005 PD TDi with the basic module and the gains are amazing.  The throttle is just as smooth as the stock car, it just has a little more overall power.  And yes the intake (just a drop in K&N) and exhaust are stock.

That module they have for my car takes it from 136 hp to 162 hp and from 247 ft lbs to 302 ft lbs for torque.  I will probable have even more power then that with the exhaust and intake mods.  

I am prolly just going to have to throw down the cash and do it.  Hey Randy got a lay-away program, so my wife doesn't notice? :P

I know 2002+ GTI 1.8T's don't pull away to quickly (stock), so I would be happy it if I was faster then a stock GTI 1.8T.  I just want to smoke my friend 's GTI 1.8T in my Diesel Wagon :D

so it's been 1500 miles on mixed driving around town (75% in town & 25%highway) and some runs up to Mt Evans to go hiking.  In the past for this type of driving we averaged about 44mpg. These past 1500 miles we have averaged 47mpg. While it is only 3 mpg better every bit helps.  In the winter we usually lose 1-2mpg because of the anti-geling agents that are added to the deisel. When we are on 100% highway we can usually get 50ish mpg.  

The new tuning module has really helped with throttle response and makes a huge difference in the mtns. I no longer need to downshift when going up the passes.  Keep in mind this car only came with 90hp from the factory, so when you add 20-25hp it is really noticible. Next weekend i will probably crank it up a little more and see what happens. But for now it is well worth the $$.

Thanks again randy!

This is a great review, I have a friend here at work with a 2000 Golf TDI and he has been kicking around the idea of chipping it. I told him about this thread the other week, so hopefully when he gets back in town I can show him the update.
