Terrano tuning

[george]

Hey... I can only post here but if you want some more power from your 2.7tdi then you need a 1k linear pot between pins 2 and 3 from the fuel pump ;-) dyno proved 30bhp and 100nm gains... enjoy cheers

Hi George now this sounds interesting, please explain more, Rick

Hi it was what I had done to up the fueling in fly by wire pumps can be done on Bosch and zexel... have diagrams to show installation but can't post them

Basically if you research vw evry mod it's the same principle

I want to know more, will get me, Rick

Will drop you an email tomorrow... the difference is nigh and day it's the same as tuning g a manual pump in effect but with be if it that it can easily be turned down or switched...

My just is with a 1k potentiometer you can adjust the effect?

Good luck, we couldn't even get a picture of the "Tuning Boxes" :doh

Ive figured it out Zac ill put pics up when I do ordered a 1ohm pot today

 

[solarman216]

A 1 ohm pot will not do you any good you need 1000 ohm, Rick

Another thing ive found is that even though the later terrano's run an electronic fuel pump the pump body itself still retains the adjustable slots in its body. Now over the years the pump wears so you end up with play in the pump shaft so in effect what happens at the front of the pump is out at the rear due to the wear, Ive moved mine on the slots about half an inch and my god did it make one hell of a difference no more smoke and the thing pulls like it never has before.

Do you have to strip the pump to do that?

 

[solarman216]

no it is the point where the pump is bolted to the timing cover 3 bolts if I remember correctly in slits on the pump, you need to slacken the fuel pipe connections and twist the pump in a clockwise direction (viewing from the rear of the pump) this simply advances the timing, but could do more harm than goods so be ware, Rick

 

[luke1987]

Rick is right it would advance the timing on a manual pump but the td27i has an electronic pump so the timing is done electronically anyway, If you look at it this way the pump will wear over the years so what is happening at the front is not necessarily happening at the rear, so by advancing the pump slightly we remove the wear. There is a section in the manual that shows how to do it properly with a dial gauge in the rear of the pump. But I trust someone who's been setting up diesel's for 30 years to do it for me . Its not a nice job to do as Rick said its slacken the fuel pipes and remove the vac pump to get at the bolts.
