Yes is a 3.5

Got bad signal can’t upload the pics, the ECU looks like a14CUX but the serial numbers aren’t right for a 14CUX. I had to send a picture of the internals to the V8 engine builders so the could work out which software it was using. (They called it a X22 early software) The MAF is off a 3.9 setup...

I have that link and gone through it already. The resistor should be green but I was told it wouldn’t cause the problem that I have. When I originally bought the vehicle it ran perfectly, I have the original MOT slips that show the CO HC readings. The exsaust was clean as a whistle, pulled like...

Try this, it was sent to me from guys that build and supply parts for V8’s. Hotwire EFi setup First things to do on a setup are as follows (and we normally do this in this order) Ensure there are no air leaks, these cause unmetered air which in turns gives a lean mixture. Check the throttle...

Hi Kev I’m down in Dorset. I have a (Blue) resister and Iv descoverd the ECU is pre 14CUX. Iv been in touch with a Rover V8 specialist that builds these & other engines with carbs and EFI systems including the ECU internals / programming. U can buy parts or complete just turn the key engines...

The 3.9 injection conversion was done before I baught the Landrover, when I got it the exhaust was clean with just about zero soot and the spark blugs where the perfect biscuit brown. Have done a huge amount of research and aperantly if you run the early set up with no lambda or speed sensor the...

Hi Kev, mine is a very early injection system with no lambda, O2 or speed sensor’s. I’ve checked the readings off the MAF (& set the O2 screw), throttle sensor, water temp sensor top of engine, fuel temp gage on front of fuel rail, fuel pressure, step up motor and all are as should be, even...

Single carb or SU’s, Which is easier to set up and which is more reliable....

Would that be a Weber 500 carburettor

Hi, Iv finally given up on my 3.9 injection system that was fitted to my 3.5 V8 Defender. When it goes wrong you can’t find anyone to work on it and the guys who know what they are doing cost a fortune, Parts cost a fortune even 2nd hand...!!! The internet is full of forums complaining about...

Il try and find some figures on the old interweb and see what the readings should be.... Fingers crossed...... Thanks

That was my next item to replace but I can’t find one anywhere. If you know of one or if anybody else knows of one for sale can you please let me know, it would be much appreciated....

Sorry what’s the TPS...?

Hi, I have a Defender 3.5 V8 with a 3.9 Hotwire injection system that was running like a dream until it was left standing for 6 months. Took it for a MOT and the Co2 on tickover is 3 time over the limit. Found the MAF sensor was not working so got it replaced, stepup motor is ok, has a new...

Okydoky thanks for the info....

Hi, was wondering if anyone is formiler with a Lucas AFH55-1 air flow meter out of a V8 3.9 discovery 1. Ever since I bought the truck it’s always run rich so been looking at a replacement air flow meters on eBay and have noticed in one of the adds what looks like a wire attached to the body of...

Okydoky thanks, Andy
