Afternoon all,
What are people's thoughts on the Motec M84 ECU for a Rover V8 powered TVR? I have been looking at DTA, Syvecs and Omex but this new M84 looks very tempting at just over £1k. It is essentially a cut down version of the M800 ECU but comes with Lamda enabled out of the box. Seems a very decent ECU, now at a competitive price point.

Also comes with data logging enabed so works with Motec's i2 software which is supposed to be very good.

looks good, 8 injector drivers so you can go sequential, but only 6 ignition so you'll have to go wasted spark not coil per plug.
but as always I'd suggest you need to find someone to map it first and then see what they like to work with.
Sound advise on finding a mapper before hand. What is the advantage of coil per plug over wasted spark?but as always I'd suggest you need to find someone to map it first and then see what they like to work with.
I am running the m800, it's spot on, I went for dual lamda, traction control and stepper control option.Of course on the m84 you don't need everything. I know now a excellent ex motec mapper.
Well worth going sequential on the fuel, not worth it on the spark.
It might be cut down but it's worth the money

Hi Nigel, I forgot you had a Motec on yours, I am not sure I can stretch to the full M800 but my needs are a little more modest. The Motec kit does look very nice indeed and that new M84 does look very good value for money. My 14CUX works very well on my car at the moment but I am looking at throttle bodies so need move away. I would rather spend a little more to get a solution which works well. Who did you get to make and install the loom on yours?
What was the reasoning behind keeping the stepper? Most people I speak to who have an aftermarket ECU have generally opted for the Bosch idle control valve instead.

Well I kept the stepper as it looks neat as the plenum is reversed, to be honest it only uses the stepper a little bit as idle is on ignition control You could of course go two wire icv.
The loom was made by a chap who did some work for emerald. You can get a terminated loom from motec that you cut to,length.

Being a mapper myself and with the huge range of ECUs out there I'd find a competent mapper that you're happy with and then follow their advice on ECU choice.
Your engine doesn't know who's sticker's on the box and the person who programs it is where the value/overall quality comes from.

Don't you guys use VEMS in the UK ? In Denmark VEMS it quite normal to come by, cheap and you don't need a tuner to map it (if you ofcause have a bit of interest your self). I did my TVR M / jaguar 3.0 V6 without any major problems.
