I dont mind* posting up dyno sheets but I'm sorry I dont post up datalogs

because what I see is an untuned AFR which was probably the stock tune Vs the tuned AFR+ignition

I remember when I did my intake manifold swap testing that alone with AFR that wasnt as far off as yours in the dynograft your showed us, ive seen around 12whp of gain which would have been more with a baseline of 10.5afr at 7000rpm . and the guy that was running the dyno was impressed at the second pull saying WoW ! you must have adjusted the ign timing with the afr.. which I didnt...

but im glad there is finnaly another company comming in the 370z ECU market !!! good job

Hope you guys do something with the HR engine !! hehe

The factory timing strategy on these cars are slightly influenced by AF changes but nothing that would show a huge gain or loss..

So changing the AF ratio will actually effect the amount of ignition timing the car will run.. we're talking .5 degrees of timing.

I played around with A/F mixture and didn't see a huge different in WHP.

On 93 octane this is the AF ratio I will be running, 91 octane will see something just a tad richer.
