I dont understand why the mivec isnt zerod out from 6000rpm to redline

 

There's something off in your mivec map that your car doesn't like. Mine has the same problem. If I try to flash a stock mivec map on the car, the code goes away and doesn't come back. If I flash the mivec map again, code comes back.

 

Checked this multiple times and cant seem to find any thing.

Tried that, still getting the code.

I have a downpipe not a dump

 

Is the wastegate being dump to the atmosphere or no?

 

sorry for my ignorance,

it's a stock 9 turbo with stock wastgate. so whatever the default is for that set up unless my tuner modified it in the tune somehow. Thought it could only be manually adjusted on the Evo.

 

Not an expert but hopefully this helps, outlined sections in your map need to be adjusted, the numbers have to transition more smoothly there are large jumps in the map that mechanically the mivec system can not keep up with and that is the reason for the code saying it's slow to react, try to interpolate between the cells or do it manually. For example in area #1 it jumps from 2.4 - 9.6 - 19.2 - 25.2, it should be smoother just my opinion, good luck, let me know if it helps.

 

With GSC cams they like some overlap in the high range plus like the gent 👆🏾👆🏾 said, definitely need smoother transitions. Do you have the autosmooothen spreadsheet?

 

Thanks for the advice! I a buddy that tunes his EVO 9 adjusted it to this



Car seems to run smoother but I am still getting the code. I will keep tweaking it.

I do not. Where can I get it?

 

Attached!

 

Still no luck with this damn code. Just so odd, for the most part the car drives fine. I'm working with another tuner and he suspects my ECU may be buggy, gonna swap with another ECU to test, will report back.

 

Figured out that my tuner didn't modify my MUT tables to actually log MIVEC so there isn't a way to know what my MIVEC system is doing.

 

Just wanted to post that I've been playing around with my MIVEC map and man what a difference it made going from Tapering to 4* at 7000 to tapering to 0* at 6000.
Top end feels amazing.

I can throw my map up but it's nothing special or out of the ordinary.
Coming from Honda K-Series playing with the MIVEC was a joy.

 

Would you mind showing us your map? I'm curious in which areas you tapered to 0*.

 

My photobucket is acting up but if you refer to this post:

It's pretty similar to Recompiles MAPS

 

some new info with my P0011 MIVEC woes.

After finally getting MIVEC to properly log, it shows that it never advanced from 13-15 deg even under full load. Idle or WOT MIVEC stays the same. For fun I changed my idle range MIVEC tables to max out (28.8) and started my car, immediately MIVEC logging showed advancement of 28.8 deg.

change my MIVEC back and started the car again. MIVEC seemed to take it's time climbing back down from 28.8. finally settled back to 13 ish deg.

still haven't gotten to do an ECU swap, but any ideas on what might cause those symptoms?
