ISCV not adjusting stepper voltage??

[warp9.9]

As for tune I do not use tune ecu but you should be able to get one off Toms site. I would look for a Jardine set up and go from there as you can adjust the secondaries open and up the speed limiter along with rev limit. I would not run it much over 6500 as the stock cams fall off after that. You really should open up the air flow with triple filters as big out does not do much good if your strangling the intake side.

Hanso might have a decent tune you can start with. He has mess around quite a bit just get one before he put the thugs on as they restrict to much.

Thanks Warp, that's good advice. I'm not that keen on changing to triples due to the extra little filters and work involved. Is the under tank filter RU-5111 a good option also, to use with a triples tune? Less work.
I just don't want to be sticking air temp sensor inside one of the triples like some do. Is it easy to fit all the filters? And will I definately notice a difference in flow with a triples tune of Toms website.

Cheers man.

Had another go with the nut at the rear of the primary stepper motor and low and behold, it did adjust the TPS voltage reading on tuneecu. The nut is not sensitive at all and requires quite a bit of movement to adjust the voltage. So now it's all set at .60v + .12v = .72v. I'm not sure about the 0.5mm gap tho. Should it be set right now given the correct readings?

Where exactly is that measured at? I can't make that out by looking at it. Is it measured somewhere close to the nut/screw?

Cheers chaps.

Further to my last post, after I made those adjustment, I reloaded a new tune and reset adaptations and even did the 12 minute after, but the TPS light just wouldn't turn green.
After previous downloads and resets the TPS light turned green immediately.

Is there something I'm missing?? Always appreciated, thanks.

5mm gap warp referes to is the clearance between the TPS unit and the thottle body surface.. what happens is because it has an offset securing screw overtightening can change the center line of the throttle spindle and the TPS key this affects inline rotation

So Warp is saying cut a shim washer from a soda can and make a 5mm spacer so the TPS **** up evenly.. remove the screw ease the TPS back a little slip the shim washer in between and replace the screw.

You would have to cut the shim with a Tag to hold with needle nose pliers untill you get the screw started.

Or don't Over tighten

If the bike is running OK it may be TuneECU software thats not picking it up or its not making the OBDII connection maybe.

I would have turned of the PC and reloaded TuneECU replug the cable and check again.. maybe you did this

Thanks Dennsell, always appreciated. I'm sure it's all ok.
