anyone installed a digi z wire in chip? (TD5)

[scottsride]

I just picked up a new diesel power up ecu wire up type.

the install notes are wronge. the wireing diagham is for a 55 pin bosch plug

has anyone wired in there own digi z chip.. its 5 wire red black white yellow and green..

i know red is 12v black is earth. white i think it maf or tps. green and yellow dont know.

I need to know what pin wires on the ecu to wire into..

i will be e-mailing the makers of diesel power for more info too. but might be faster reply on this site..

You need to get a copy of the electrical library and wiring diagram pdfs both which come on the RAVE cd.

I thought AMV told you the vehicle was already chipped? Are you 100% sure it's not?

[scottsride]

100% sure.. I got an email back from diesel power the makers of digi z units. They i have the wrong unit for a td5.. So ill be getting my money back.. Now i need to find another power up chip that comes with a td5 install kit.

SUCKS getting the wrong parts and info from sales ppl.

With LR stuff it seems to pay to deal with people who know LR's.

You'd be better off with a rechipped ECU:

Engine control units (ECU's) for Defender / Discovery - Upgrades - Triumph Rover Spares South Australia (http://www.triumphroverspares.com.au/page.asp?parentid=3&productid=1)

The other route is to track down a reflashable ECU to suit the car, then getting a remap. It ends up more expensive but is also far more flexible in that purchasing another the remap is cheaper//easier than buying a second chipped ECU.

Intercept boxes aren't a good solution...

Go with Offtracks advice...

[scottsride]

Thanks guys. Phone calls ahead for me.. I think flashable is the way to go..

Ya 25% more power. I got a davis chiped ecu fron ritter.. But now my turbo bearnings scwill when ever i drive harder.. Hopeful i can get a serice kit for it.

Was looking for random stuff on ebay. And there is a full rebuild kit minus compressor and exhaust wheels. Was only $88 delivered (well to me atleast).

Hoping this is my issue. As I only get the squeal from 2000rpm and is gone by around 2700rpm. And then dosent come back until revs go to idle.

Qn for the experts. Does the turbine shaft need to be re-balanced when rebuilding the turbo?

[scottsride]

Mine is from 2000 to 2700 aswell.. But not at idle.. High pitched noise.. Thanks for the link

It's most likely a warped exhaust manifold. Pull the heat shield and check around the manifold for signs of soot and broken studs.

Ill have a look..

Our turbo units have Oil suspension bearings....

As mentioned by others the rear most (or front most) exhaust port is leaking at the gasket - most likely a warped manifold...

Can you clue me in on how an exhuast leak can make the turbo screem?

[Tombie]

Can you clue me in on how an exhaust leak can make the turbo scream?

You've just chipped the vehicle...
Its now making boost quicker....
The manifold was 'already' leaking...

Now that you're boosting up quicker / a little more its not the turbo screaming - it will be the manifold squealing between the gasket and the head/manifold.

What makes you so sure the turbo itself is squealing?

[scottsride]

The guys at ritters who installed the chiped ecu think its the turbo.. I havent had time yet to look at the exhaust manifold..

And to me it does sound like a bearing noise. Never heard of a manifold screeming..

[OffTrack]

Do a google search for "td5 manifold squeal". It's often diagnosed as faulty turbo, squealing accessory belt or bearings.

It should be easy to check the bearings. If you pull the intake hose you can check the rotor for play. If it blades touch the housing you have problems. The rotor should spin freely. Expect a bit of slop because the turbo has plain bearings which rely on oil pressure for lubrication. With the motor off there is no oil feed to the bearing and you get play.

Had a look over the exhaust for leaks. Cant see anything suss.. But i did read over my service history and found that the owner b4 me had the manifold machined so maybe it is warped and they tried to fix it insted of replacing..

The other issue i had today is took off flat to the floor. 2 warning lights flashing sports and some other one going to gether. It went away after i stoped and drove off agian.

The book say auto elec isue.. Its a new auto fitted 5k ago so i dono whats up with that.
Probly over heated abit maybe?

[OffTrack]

Machining is the standard fix for warped manifolds.

M&S can be a range of things not just auto electrical. If you have gone overboard on the chip you could be exceeding the torque limit for the auto for example.

[Tombie]

The M & S is exactly that in this case - too much torque through the transmission and its gone into limp mode.

A restart clears it - if it happens a lot, it can be dialled out by a tiny adjustment to the wastegate. Or you can get a later Auto ECU which has slightly better tolerance to high torque readings... (This has a limit still, just more hysteresis..)

[scottsride]

Thanks guys..

Know i dono if i should go for a standard 2nd manifold or go get one of the davis bigger sized ones.. Ill look more into my options over the wk end..

As for the warning light over powering it makes alot of sense.. Good to know my limits and yeah maybe ill back of the waste gate a 2 turnes.. I did turn it up 6 half turns..

[scottsride]

Well found and fixed the screaming sound.. I took the exhaust gard off cleaned the manifold thought id check the exhuast studs and they were all loss.

Happy i dont need to spend on parts.
