New ecu and varioram law modification
Hi
i will install an ecu and ask my tuner to do the proper optimisations
as the varioram is managed by solenoids and rpm to open or close the resonance flag / pipe length
can i imagine they are ways to improve and get some free hp ?
like for a vtec when you start it earlier
perhaps having the tube to shorten at 5000 or 4500 rpm instead of 5200 can give good results ?
thanks for your feedbacks

I doubt there is anything to be gained unless other components are also changed, specifically the camshafts. In the UK there resides a wizard who can get around 15bhp usually by reprogramming the ecu on an otherwise standard engine but would you notice?. Reports say throttle response and flexibility is improved but in most cases improvements are found due to getting the Vram working as it should.

Thanks
i already have some mods and run 310 real hp
i ve seen the new ecu give nice possibilities to increase torque
same using modern ignition
just i never see a post or someone working to improve the varioram itself

What mods got you to 310?

Well
the schrick cams for hydrolic lifters
enlarged tb (double as it s a vr)
cargraphic 200 cell and exhaust
plus huge work on solenoids vacum lines etc to be sure it works
and for sure a live mapping with a good tuned shop (manage competition cars / half of their business)
i will look for the dyno if you want
initial was 270 from memory cause vr did not work at high rpm

here is how to make more power with your after market ECU https://www.drivingline.com/articles/air-cooled-911-intake-revamp/ I'll be doing this this winter. I alread have coil on plug setup with AEM ECU. I'm just waiting to get it. It's on order so I'll let you know how good it is next spring here is where I got it from https://rasantproducts.com/engine-management/911-itb-individual-throttle-bodies/
