Thread: Gutless TD5

Hello,
Mine is the same I have a auto and was putting it down to that. I am thinking more of the TPS tried to get it off the other day but gave up was given better way here on the form might try tomorrow. I only get 4.9999 volts at the pedal when it reads 5 volts goes much better. Whereabouts in Perth are you ?

Hi mate, It may be worth having a chat to Andrew at Les Richmond Automotive in Thomastown, Victoria. They have done a lot of work with re-mapping the TD5's with VNT's. I have driven a vehicle that they have re-mapped and it is incredible how much power it had low down... Cheers, Aaron.

Generally a TD5 is gutless below 1500-1800rpm.
Autos are generally better as they deal with the turbo lag better.
Not sure what you are expecting.
Is this a change or just since you have taken ownership.

Thanks for the replies guys, please keep them coming , i will try anything to get this solved!
The gutlessness is far beyond the regular low rev lag. I have owned an identical vehicle and towed the same boat easily previously, i also had a 200tdi bog standard defender that had more go in the low revs than this.
I will check the TPS! Good tip , thanks.
This vehicle was an auto that i have done a manual conversion on !
It was laggy with the auto as well but i figured the auto was on the way out 250 000km and had a few issues with the xyz and so decided i would swap it over as i had all the parts.

Maybe check the waste gate isn't jammed. My D2 had something similar, also threw a heap of over boost codes, which were (i think) mis-diagnosed as a faulty MAP sensor. When we finally figured out it was the waste gate (as I always suspected) it made sense. NO go down low, smoke from over fuelling due to low MAP as the turbo had no exhaust much to set it spinning. Once it did get going, it went like a train, but keeping it on boost was REALLY hard.....
Good luck!!

Thanks Matt, although the vnt is new! But i guess it could be faulty from factory, i never really thought of that .
I had a look at the TPS readings at idle as follows;
Pos.1 0.743, Pos.4 .295, Pos.3 4.677 supply 5.000
Full throttle ;
Pos.1 3.750, Pos.2 1.358, Pos.3 1.368 supply 5.000
?

what size tyres are you running?

When you did the conversion was a manual ecu put in or was it just changed in the bcu?
I would start by unplugging the MAF is it no different or better it gives you a starting point. EU3 engines suffer from MAF issues a lot worse then EU2 engines.
