Thanks for the comments guys, I have seen some very 'interesting' approaches to ecu assembly even from the 'pros'.... every one make mistakes but thats what quality systems are there for. Every thing we do gets fully tested and signed off before release and normally this is done by Mike (so someone else tests your work), its backed up further by a year warranty. This has eliminated faulty items being sent out to clients, and is something imo every company producing things (little or large) should do.

Hey Rick long time no speak.
For us £250 is a subsidised price. We don't mind making the mapping fairly cheap as 9/10 we have already supplied the ecu. Further more because we only map pretty select models the cold start, warm up and idle control is 99% taken care of by the base maps we have made for various engine specs. Most only need a few tweaks on the day. Cold start for instance as you know doesn't need to be OEM perfect to work well if you don't care too much about emissions on warm up.
Boost control is setup on the dyno, as is the transient fueling both of which are infenintley simpler on the dyno. Accel enrich for instance takes 10 mins, on the road this can take a whole session, boost control takes a few pulls and then some road testing to confirm.
Leaving the majority of the tuning session to power tuning an part throttle tuning.
To be totally honest 80% of the people that see us have already done the low RPM off boost tuning as well as some on boost tuning, and some do a really good job! Which gives us loads of time to sort out the ign advance tuning etc, this definitely cuts the time an improves the results!
Recently however we did a skyline, we didn't have any base maps for it so it took 2-3 days (on and off) to get to a standard I was happy with, and thats with a further dyno session to go
However (mildly off topic
) the chap with the skyline engine races competitively, with the new ecu and a map which is half way done (low boost) he has already knocked over 1s off his last years best time which im chuffed to bits about!
However we certainly didn't charge £250 for that, so I guess the price charged really reflects the company niche and the availability of varied base maps to start from.
