These are my maps for a popular OEM BOSCH ISV (if you need the part # let me know).
I have adjusted the internal plate to be totally shut when ISV is not in use, not 30% opened like it is by default.

Re: Idle Valve maps (BOSCH)
Nice work!
For the benefit of others, the valve you are using is a Bosch 0280 140 512, which is a notoriously tricky valve to control, which in part is due to it's massive flow!
Also worth noting this valve may need a 1N4004 diode across Signal and +12V on the S80. Mine certainly needed the diode otherwise it didn't respond at all.
Max duty = 80%
Min duty = 30%

Re: Idle Valve maps (BOSCH)
Nice - I have a Ford one but I might try this one out I currently have no ICV installed.

Re: Idle Valve maps (BOSCH)
good info i have 4 of these laying in my box so will find a use for one of them.
Re: Idle Valve maps (BOSCH)
Do you need enrichment compensations to go with this map? My engine hunts and runs lean with these settings...???
Re: Idle Valve maps (BOSCH)
Yes. More air = more fuel needed to avoid a stall. You can enrich the base map or use the enrichment table in the ISV parameters page.

^above - only if you are TPS as load with no pressure compensations whatsoever. otherwise leave the table empty for obvious reasonsVR6Turbo wrote:Yes. More air = more fuel needed to avoid a stall. You can enrich the base map or use the enrichment table in the ISV parameters page.

Re: Idle Valve maps (BOSCH)
I was TPS with MAP compensation and it needed some enrichment as the valve opened. MAP as load I can understand comps not being required, but c'est la vie, some motors do 'ave em!
