I did the initial map on my cossie on its new modified ECU this weekend.
I cant get over what a truely amazing product this is!
I just SO wish that the LET was considered a big enough market place for someone to develop something similar for it!
For those who dont know (which will be everyone i guess as there are currently only two of these ECU's in the UK, lol) the RP Labs product is basically a modified cosworth ECU.
What they have done is altered the hardware to allow the use of reprogrammable chips instead of the usual "write once" chips, and then altered the diagnostic port to allow two way communications.
This results in software that can LIVE map the original cosworth ECU, it really is fantastic, its just SO easy to map quickly with it.
Such a shame the LET isnt taken that seriously :(
