a trip to efi-parts

[steveT2]

i know its not a 5 but thought i would put a vid up of my s2000 that replaced my 5,it started out as a tottaly standard,24,000 mile s2000,that soon changed,after a month of ownership i ordered a tts rotrex s/c kit,aem ecu,dms 76r full 3" exhaust/manifold,750cc injectors,aem fuel rail and fpr.
i origanlly had it mapped by someone else,where it made 364bhp@10psi,and i wasnt 100% happy with the map,so i took to scoff

the final outcome was 420bhp@13.5psi:eek:and a much better map

You can see the vtecs effect quite well on the graph, from 150 to 200 quite a jump. Is it dificult to map around that effect?

Well done steve / scoff good result there.
Ps thread hijack steve your r5 turbo 2 tdc is awesome. I'd love to read a project resto thread on it.;)

Thanks steve :)

The AEM deals with vtec a bit cruedly, just a single % enrich, which seems to have a delayed effect so you're left with a bit of a squiggle in the AFR. You don't feel it though.

Incase anyone wonders, that roughness between 2000 and 3500rpm is actually the dyno, not the car. The engine doesn't really fluctuate 25hp ! For some reason on some cars the dyno screws up at low power output, ie the start of the plot. It's a closed-loop thing. Superflow sent me a new set of config files to improve it (it must be a common complaint!) but it hasn't helped much.

good going, the honda engines seem to take some serious abuse.
