Discussion
Firstly my understanding of engine managment is very limited.
I need to run a flat shift system on my race car and have been informed that the mbe will not support this. So ive had a look around at other ecu options. What im struggling to see is apart from enabling the flat shift function what will i actually gain from having a good ecu??
Also any views on the various ecu's out there..
Thanks
Mike

Again, I'm amazed MBE cant to this, must be pretty crap really.
DTA has this feature, and I'd have thought almost every aftermarket ecu in some shape or form.
There's no doubt Motec is good....but carries a hefty price. But more importantly, who will be tuning and installing it ? You need to use a system that your tuner is able to work with

I'm amazed the MBE can't do flat shift either, but by all accounts it's difficult to tune.
Have a look at Emerald. I have briefly played with these on 2 different cars now (AJP Griff and supercharged MX5) and found them to be quite good. It's a shame there's no inbuilt wideband controller, but at least there's a 0-5v input for a separate dedicated controller to use.

I can second that. I recall a turbocharged engine with one of my big valve heads that was detonated to the point of cylinder head gasket destruction (and considerable damage to the head itself) by a rolling road operator who didn't realise the boost retard settings in that ecu were a percentage of the base map ignition timing rather than actual degrees of retard.DTA has this feature, and I'd have thought almost every aftermarket ecu in some shape or form.

He set up a base ignition map, then added what he thought was 10 degrees of high boost retard which was actually only 10% of the 30 degrees of base map advance i.e 3 degrees. It ran fine without boost but detonated like a bar steward under boost so he kept adding what he thought was more degrees of boost retard but which was in fact only a few extra percent of the base map 30 degrees. Before he'd got the boost retard anywhere near what it needed to be he'd run the thing for long enough under full load it expired in a cloud of steam and smoke and had to be trailered back home on the back of an AA truck.
Needless to say he didn't pay for the repairs.
Mind you I also have to say that's a damn silly way to design a programmable ecu so I can understand his confusion but then it was his choice to map with something he hadn't used before and didn't read the instructions for properly.
As for ECUs to recommend I'm not up to date on the current state of the art but I've never seen a DTA system which didn't do exactly what it said on the tin and I've never seen a failure with one. I'm sure others are also good but you stick with what you know. I've seen god knows how many failures with one of the systems previously mentioned in this thread although maybe they've got their act sorted out better now.

There could be a way to do it on the cerb ecu Mike, who told you it couldn't be done ?
You can flat shift without any rev cutting of course but it's not too kind on gearboxes so some kind of rev limiting for the shift period is desirable. seems a shame to change ecu if you dont have to ..

Have a good read through. I think they're bloody fantastic, and genuinely do self-map for fuel.

Suppose the S6 would probably cover it.

Depends on the engine you have, the ECU you choose and what additional hardware you want.

My MBE 992 supports flat shift, launch control and can also blip the throttle on down shift. Have a chat with Steve at SBD for more into.

We fitted a MoTeC M800 to an Aston V8 Vantage GT3 car running a Drenth sequential box. Ran flatshifting absolutely perfectly. Providing you have the signal coming from the 'box for up and down shift, you can configure both the upshift and the 'blip' on downshift with the MoTeC.
If you are going to the expense of a sequential system, you have no doubt spent funds elsewhere ie engine etc. It's certainly worth investing in a good system to control and look after your investment ! MoTeC has it's reputation for good reason.
