TVR Power RV8 MBE ECU

Looks interesting:

I wonder how this compares to other after market ECUs?

I also have a Tornado EPROM in my 14CUX and I am considering upgrading to the Bosch MAFM, red top injectors and adding ignition control using the Omex 200 unit.

I would like to see how the MBE unit compares to a 14CUX ECU running the fuelling and OMEX 200 running spark. I also note that the MBE package gets rid of the MAFM in preference of a TPS. I think I would prefer the fuelling to be controlled by the a MAFM from a drivability point of view.

^^^^^I'd say that's a pretty fair assessment of things.

+1 Good post

I would certainly like to know more about it. I am the first to admit that I do not know much about mechanics and ECUs therefore I would not consider the likes of MS. I prefer best of breed, fully supported products installed by TVR professionals, fit and forget so I can enjoy driving the car and not worry about constant tweaking.

I am still a bit confused about the absence of an MAFM on the MBE package. I thought you needed one of these to ensure 100% driveability in all conditions.

That is very interesting about MS and the Ford Mustang MAF. I don't see how TPS alone can match the drivability and compliance you get from running a from a MAF.

I am not sure who Dale is but a MAFM is a Mass Air Flow Meter... it is used to by the ECU to analyse the mass airflow and adjust the fuelling.

The wiki article is quite good so may be worth a read if you are interested. I believe the orginal Lucas system uses the Hotwire system.

So has anyone had one of these ECUs fitted yet then?

I'm having some fun with Matthew Poxon as he has a lovely Griff that's crying out for the Mbe,, his trouble is he's got a good set up as is,,,

I'm living with this new Ecu every day and it just gets better and fills me with joy every time I fire it up.
I've done 7500 miles in about 8 months including a 24 hr drive from the midlands to St Tropez in France ( 964 miles in one day )
Faultless so far.

Holy thread resurrection, are you on commission Alun? As you can see I have been interested in the MBE for some time.... since 2012!!!

Mine is running perfectly at the moment fuelling wise so it is difficult to justify a change, I'll see what she is running like at the end of the year after a summer of track abuse and make a decision then.

7500 miles in 8 months, that is good work sir. Good to see you are using the old the girl.

Looking forward to the Lotus track day this weekend, will be the first track day since the gearbox mods and new cam so a bit of a change to what I have been used to.

280BHP at the wheels is more like 330BHP at the flywheel! That is a really good result, more than my now healthy 500!

Will be interesting to compare graphs at the Growl Rolling Road this year if you are putting yours on.

It was indeed mapped on Dom's rollers.
