rover 75 cdti tourer remap
 

hi to all
i have a question for big russ
reading the threads on this forum on remap the ecu the facelift diesel has to have the ecu remaped so is it done on the T4 with the X power software and can the bhp be increased from 131 to 160
david

XPower upgrade (DXT0002W) takes a 116PS diesel to 131PS (114 BHP to 129BHP)

If you look at the tune assembly with T4, or indeed the VN string of ZCS coding it will tell you if a car is a 116 or a 131.

The 160 upgrade can also be applied using T4, but you won't be able to buy the disc to do so, as it was never made available for general release ;)

Brian :D

I'm not sure of the ins and outs of how it is done, but I had my 131 remapped to 160 by the legendary MarinaBrian, and it's brilliant, thoroughly recommended.

Hi David, the diesel can be re-mapped with the 160 map from either 116ps or 135ps ;) We do use T4 and custom software if the car is present, otherwise we have dedicated software and equipment to do it if the ECU is sent by post.

Russ

It is well worth having it done, totally transforms the car. Makes it the car it should have always been.:D

thank you russ for your reply how much would it cost to remap the ecu and i post it to you and would it cause any problems the car has done 1002,000
david

It shouldn't cause any problems we've remapped quite few with more than double that mileage without any issues.

I've sent you details via pm.

Russ

Wow.--That's over a million miles.------:bowdown::bowdown:

One million two thousand to be exact.----:eek::eek::eek:

my mistake 102,000

Maps depend on how much torque you want. The "160" map can produce around a 20% increase in peak torque. Or others offer a 50% increase in torque.

Torque is what you feel :). Some people on here will say that a clutch can't handle the power, but it definitely can (providing it isn't already knackered).

See below image of a dyno printout achieving about the most torque you can get without smoke. To get more power a larger turbo needs to be fitted.

Interesting graph, what units are those then? Smarties or liquorice all sorts.?

Lbft and HP. No need for comments like that. It’s an actual printout unlike the “160” ones.

:

On a serious note, I'd like you to calculate the maximum permissible torque transmission of a CDT clutch.

The figures are

A driven plate with external diameter of 228mm with a friction coefficient of 0.25

An axial clamping load of 1484 lb exerted by the pressure plate


No flim flam such as your clutch will be fine if it's ok, but if it's knackered it won't etc will be entertained, and your working out figures must be shown.

Brian :D

Xpower upgrade
 

The genuine XPower upgrade only unlocks a certain thing in the ECU.
All 116 are capable of 135.
All the upgrade does is remove a "gateway" to the full map.
The disc on it's own is pointless. That just allows T4 access to an area usually locked. Every disc is the same.
Now comes the clever bit :D
If you ordered this from XPart, you would receive a disc, instructions, a certificate which in theory you send to your insurance company and a sort of metallic sticker that should be attached just above your VIN plate on the A pillar. What you also get, is the Unlock code for your VIN !
These are unique and are generated by some Pixie at XPart :D
The 160 upgrade was never official but I understand it works well. Just don't ask XPart for the 160 version :getmecoat:

If you really know what you're doing on T4 you can access the unlock code for the 135 upgrade, you don't need X-part to generate it. But the car has to be present. ;)

But if you do go through X-part you get a nice sticker for your B pillar :getmecoat:

Russ

Apologies. I meant B pillar. But this was the official MGR way of doing it. Nowadays there is various ways of upgrading stuff. But people want OE !!:getmecoat:
Personally, I would not bother with a 2000cc diesel if you want some HP and grunt.
Not in a car the size of a R75.
Never going to happen.

Even my ZTT 190 would not blow you away, performance wise.
Compared to a Skyline for example.

Thats a thought...
take the engine out of a Skyline and match it to a Kawasaki Z1000 engine system.A
Wow. It has been done by the way.
Was put into a ford ute pickup . 0 to 100 in about 6 seconds.
And yes, it was street legal ! :bowdown::bowdown:

re map
 

Thanks for sorting it today, my son Steve says the car is a beast, and I have to agree. More go than our last 2 litre v6, doesn't sing the same noise as a V6 on full throttle but really does go. Should have done this out of the factory when new!
