emerald ECU,Trying to start engine.

[robin377lotus]

Hi can anyone help me, that has knowledge of the emerald ecu. I have fitted a ford modular 4.6 32v mustang engine, with a xkr supercharger in to my tr7. Emerald have supplied a base map, and i have had it running. But it is difficult to start, almost impossible some times, it tends to try to fire then floods, as the plugs come out wet.Compression is good and have had it on a oscilloscope to prove the wasted spark system is firing at the correct time.I believe it is a f/a rtio problem combined with iac cold start. If anyone has the experience
and time to help, so i can get it going to take it to a rolling road to be mapped. I will pay for the help, i am by landrover solihull.
much appreciated.

Thanks for all the advice,under 3000 rpm it pops and bangs, lots of flames(over fueling), over 3000 it comes to life. reduced the fueling using fuel trim (key 3 ). As said it is almost impossible to start,have used around four sets of plugs (including drying them out).No lamber sensor.
So it is beyond me, if anyone can point me in the direction, some times you just need some help. I am at that point.
thanks

Hi, i built the body to look like the ADA engineering/janspeed lemans car from 1979, its all steel. I do not know peter ,who is he? i take it he is into tr s? The gearbox is tremic 3560, axle is sd1 at present , but know it will not last long. I do have a jag power lock to use.
I would take it to dave walker, but i just want it running just to make sure nothing is going to fall off.It is a long way to go if he can not complete the mapping due to minor issues.

Bert still owns the car i think, but did have it up for sale. Not sure if it sold, think it was £100k.I have got a 285.1 sd1 but do not think it will take the abuse. I did built a 7 with a tomcat t16 turbo engine, that use to spit out sd1 diffs, and a couple of tvr,lt77 boxes.
Dave has been help full, as he knows what i am trying to do, he has suggested some one closer, but i thought if someone was close to me and had the knowledge it would save me trailering the car, just to get it to run.

Hi, i did say in my original post,because i know that is a key piece of information. Solihull by landrover plant. B92. thanks

I did discuss this with emerald when i purchased the ecu,because i thought the same as you. I did weld the bosses in to the exhaust manifolds From what i remember they said you do not have to use one to run, but they could hook up one to map it.
Any way i have messed up by having it running,and adjusting the fuel trim, i pressed enter. Now when i look at the fuel,ignition and cold start pages.they all have zero in all boxes. So clearly i have done something wrong and lost all info.I take it they should not all read zero.
I now need to wait till emerald are open, in the new year. Will ask them to e-mail me the base map, as again another cock up not saved it to pc.

The le mans tr7 is a fantastic car, pity it never qualified. Over 200mph in a tr7 in 1980, what a blast.
Anyway thanks for all the useful comments,looks like i may have to start reading.

some not very good pictures of my attempt at building a tribute to the le mans tr7, first engine was a rover v8, twin roto master turbos.

every time i load the side image it turns upside down, its the right way on the pc. so loaded this one.
Have you got the Ls tr7 on the road? What ecu are you running? i would think it would be a tight fit, just like the 32v.Take the skin off my hands every time i work on it.

[robin377lotus]

boosted i have sent you a pm.

[robin377lotus]

Thanks for that info,I would love to take it to emerald and i am sure i will. For my own piece of mind i need it to run it up to temperature, and ensure the rest of the installation is ok, eg gearbox and final drive.
I appreciate that you have spent the time telling me, where i may have gone wrong.

Hi all, Dave from emerald has sent me a new base map, loaded it turned the key and fired first time, fantastic.
thanks for all the positive info.
