I rate jdm plug n play ecu's highly, i think they are bang on for ct9/hybrid set ups. I run a blitz access myself.
There are plenty of parts ive not had to touch like fuel pressure regulators, fuel pumps, map sensors etc. All would need upgrading for emanage i think.
Also they are pro for ease of changing set ups, i was running a hybrid which shat itself, so just put my ct9 back on and off i go, no need for expensive remaps, same when i changed air filter and intercooler setup's etc.
Also a major plus to them is fuel consumption off and on boost, with my standard ecu most id done to a tank of fuel was 300km, with the blitz ecu i can now do 480km to a tank, so in time its going to pay for itself on money i save on fuel.
Anyway i have some power figures from when i had it on a ct9
My spec is
CT9b with ported wastegate
Jam Manifold
Autobahn FMIC
Decat
HKS Hi Silent exhaust
Front mounted air filter
Blitz access ECU mapped for a K1
Gizzmo IBC
Running over 1.1 bar boost
I know some people will disagree with them, the above is just my opinion, if i was after big power figures i wouldnt bother with them but for what i want there perfect.
