Depending on where you source the engine from you may have changes on the engine and sump. My mockup engine came from a step speed mgf and the three bolt holes in the block for the right hand driveshaft support bearing were not drilled to size or tapped out. On the sump the holes for the lower...

I dont know what year that V6 ECU came from unfortunately ( eBay purchase) but it's clearly unhappy with something. All I have thus far on the bench is the gearbox ECU with selector inputs connected with the instruments and engine ECU. I do have some load resistors on the gearbox ECU outputs (...

So I tried a few ideas out in my actual td4 auto to see how things would work or not... See attached the picture of the auto ECU I have. From top left is a V6 Freelander, top right is td4 Freelander and bottom row are both r75 petrol 1.8 All work correctly,changing does seem to differ as we...

As I said above I hope a log of a running vehicle will reveal the traffic that's missing. I have td4 auto which I will setup to log . I know the 1.8 cluster works fine already so that data is definitely the same .

No not at all. Both gearbox ECU send the same basic data packages on 0x43F . I have not seen any specific replies to the gearbox ECU by the engine ECU. I have tried both a manual and auto r75 engine ECU and also a 1.8 Freelander ECU with same results. But the Freelander instruments ALWAYS...

The gearbox ECU must also be coded to if they are in a Freelander or r75 . I have still not been able to confirm if the manual sport shift we have in the Freelander will work on a r75 gearbox ECU . All my testing is done on a bench loom with only the engine ECU, gearbox ECU and the Freelander...

Do I assume this info is captured using the scan tool you sell? I have not seen any replies yet from the engine ECU to the data the gearbox ECU is putting out but it may be the vehicle needs to be on the move for that. One other issue you might be able to help with is the coding of the jatco...

No that's it , on the bench so far I haven't seen any "different" data in the messages from ANY engine Ecu in response to the gearbox ECU. According to the jatco info I have there should be more messages seen FROM the gearbox ECU. This far I have seen ; Gear lever selector position. Gearbox...

I tried an experiment with the auto gearbox ECU connected to the rover 75 auto and to the Freelander 1.8 ECU. I logged the data traffic over the bus and the gearbox ECU always sent it's data ( which the instruments showed). The gearbox ECU uses 0x43F . This was the only extra can id transmitted...

Wanted to share some testing results . I have an r75 nnn000110 ECU on my test rig along with a 1.8 Freelander clockset. The r75 gearbox ECU shows gear position on the instruments no worries , but the tip tronic selection and sport mode of the Freelander will NOT activate :-( I tried the petrol...

I just bought a V6 box ECU to add to my collection , so yes it will be interesting to see how the shift points differ. It will be also interesting to see if the r75 box ECU will have operational steptronic , as that will give a third box ECU option. Unlike yourself I m using a r75 1.8t gearbox...

Which model auto ECU are you planning to use? From what I understand they are all(Freelander and r75) the same hardware but have differing firmwares to suit application and engines , this gives at least 5 variations! I was thinking the V6 version should give higher shift change points then the...

When I put my 1.8 petrol cluster into my td4 automatic all the functions (including auto messages) worked , but I couldn't check the AC as my Freelander AC needs a regas. The main issue with using a td4 cluster is the rev counter has a lower scale. Something I did consider had that test not...

Pscan you mention tapping into the can wires at the instruments. If you look at the schematic (Freelander) it shows the instruments can going to the abs and then another set of pins on the abs going to the engine ECU. Do you know if the abs is relaying the can signals or are those pins...

I don't know if this is any use or assistance, but the piccy attached is for r75 .

I wondered how the 1.8 manual cluster would work. So I plugged it into my 2001 td4 AUTO to see. Everything works as is , gauges read totally the same, gearbox position displays, no amigos. Everything is Spot on. So I can only assume the can messages are being sent out correctly. Unfortunately my...

So according to my schematic, On c0230( instruments) pin 9 the AC pressure sense sends a 0-5v signal . The instruments sends the data over canbus to the engine ECU for ideal control, cooling fan speed control and AC compressor clutch cutout. Also on c0230 pin 20 the AC evap sense input is sent...

According to the schematics the two a/c switches are connected to the instruments which sends out data for it over the canbus so the engine ECU knows for the idle and a/c clutch operation.

Watching this with interest . I am modifying a kit car using r75 1.8t and autobox but using many Freelander 1 auto bits too. I am using a facelift fl1 gear selector and box ECU so I get the sport shift(r75 didn't have that) With a mgf stepspeed steering you get flappy paddle shift too! I have a...
