Started out with 4.0 V8 with SAI which died. Reconditioned (non-SAI) 4.6 V8 fitted in October, 1200 miles were done on petrol only with no apparent problems average mpg was in excess of 18. At 1200 miles a full service was carried out and the LPG recommissioned, shortly after this the...

From Auto-Express: So I would imagine not enough improvement on a Discovery to really notice.

Fair enough, bigger intercooler makes a lot of difference, my point was you don't normally get 170 plus just from a remap which you have upheld. 163bhp is a 3.5, 3.9s and 4.0s are both over 180bhp and anyway I don't think your 175bhp will be much of a match for my 210-220bhp, but thanks for...

I doubt that you have much more than 160bhp unless you have the stage 2 tune ie larger intercooler and boost upped as well as the remap etc. My brother in laws has been measured at 156 with a stge1, de-egr (added nothing to his) and exhaust sorted.

A) we don't have the ECU, Lynx do. B) ECU Doctor is who my garage usually use they don't do DII V8 ECUs Thanks though.

Beginning to think the old girl is jinxed, the replacement ECU has got lost in the post :mad: Seller has apologised and given me a refund but means I need to find another one and I bet it won't be as cheap either!

I don't doubt it mine did 1500 miles before we encountered the problem and I know someone else who is running a 4.6 with stage 1 heads and uprated cam on 4.0 fuel map without any issues.

Well I have given up on Lynx too, brought a s/h one that is supposedly winging it's way to us. Hope it's the right one though Rave lists NN100460 & NN100640 when you put my chassis number in, couldn't find any 460s so I have brought a 640. Lynx really haven't got a clue they said on the phone...

Latest: the garage have just sent me a recording of his latest phone conversation with Lynx, scary to say the least the fact is the guy doesn't care, it will take as long as it does and says it's all our fault as you can't run a 4.6 with a 4.0 ECU. From the Rave: A single ECM is used for the...

Surprise, surprise another week passed and nothing! Time to get heavy methinks.

Well mine is still not back, it's been a month now, although they said on Monday they just need to locate a part now which will take a day or so, so hopeful it will be back next week.

Did that! Alive Eng brings up nothing LR related, adding Land Rover brings up TD5 Alive, thought they just did oil burners.

Cheers. Irishrover I take it is the user on here of the same name, but Alive Eng?

Sent my ECU off to Lynx Automotive for testing and they have come back with it's complex repair, may be done next week, this has been going on for a good few weeks now and I am not very happy. Anyone had any dealings with them or know anything about them? Also anyone know where I can get a good...

Makes little difference £245 without and £235 with.

Right we have had the old girl on Testbook and all clear :confused: Would the open loop running, and no fault codes point to a faulty ECU?

Sale of goods act, not fit for purpose end of story. Take it back insist on a warranted repair or you money back.

Thanks, what I am probably going to do is get it up to the local (27 miles away) independent LR specialist and get them to do a diagnostic, I beleive they have Autologic LR diagnostics.

Garage std diagnostic kit. Garage are telling me they go from .4 to .8 as far as I am aware they don't got to 0. Sensors are genuine parts from Rimmers in LR boxes. Cheers.

Right we can't get the old girl to go closed loop, this means we are getting about 10mpg, reduced power and occasionally poor running. Lambdas were fixed at .5 so we have swapped them out for new ones and they now flip between .4 and .8 but no difference to the running. No other errors are...
