The ecu on my stratos replica uses knock sensors but quite a lot of people don't use them.
The knock control on my omex actually takes a 'measurement' of knock at idle just to get a base line reading this is then set as 'zero', after that it will then take a accurate reading. Without this facility the sensor can actually detect knock when there isn't any, just the engines usual clatter.

Excactly Strat24v. The same calibration has to be done when mounting the Vems, but lots of attempts have shown that the simple way to do it is to hit the block with a wrench and record the Hz off the impact on a laptop. Then put that into Megatune, and that is it more or less. But its probably harder than i make it sound, haven't tried yet!

Bit off topic strat but if you didnt know you can link omex with racelogic DL1 data logger to log engine parameters with the gps data. Only found that out at autosport - and bought one for my 600 as the lesser model had no datalog.
Regards the knowck sensor the set up is the same for the omex hitting the block. I will wire up the coupe sensor and decide whether to play with the knock.

Does your speedometer work with Omex/Motec? Because that is one of my concerns when mounting a new ecu system.

Surely the speedo just reads off the gearbox. It's got nowt to do with the ECU.

Given that the 20VT uses a Bosch Motronic ECU and that Bosch do a mappable motorsport range can the two be interchanged easily enough? I wonder if there is much advantage to be had? http://www.bosch-motorsport.de/content/language2/html/2953.htm

A large portion of the cost is in mapping. Looking at some of those prices it'll be cheaper to get MoTec!

Yeah, the price does work against it a bit!
From what I can make out this is a step above what Motec does though, it's probably more at home in the likes of F1 or Le Mans racers, maybe a bit more than we need eh?! I did think it was interesting though and never knew that Bosch had a Motorsport division.
On the cost of mapping and speaking from my experience: If you can beg or buy cheaply enough a base map to get your engine running then you are 75% of the way there, then you can either fine tune it yourself or (like me) get someone else to do it - It only cost me about £300 to have mine done and it gives good power and economy, still needs some cold start adjustment, although this could be put down to hard plugs and an old fashioned distributor system.
