Red face B58 surging using Map3 - 03-22-2018, 05:00 AM

Hi all,

I would appreciate comments on the WOT run below. I use 93 octane exclusively. Power and responsiveness is great but the surging is worrisome.
How can the surging best be adjusted?

Thank you.

bro saw your logs.
saw some worrying Ign1: Ignition Advance value large drop around 4400-4500rpm 13.5 drop to 6.5 . and another one at 5000 rpm from 13.5 to 4.5
trims are high too.

i would suggest up FOL to 70 log and see.

and suggest to add the EWG and FF wires too which can help lowering ur trims and better wastegate control.

Maybe Steve and Terry can help abit.

The DME is wobbling its boost target, likely due to a fuel cap, and the map3 boost request due to cold weather.

For starters do a log on map4 (stock) and map1 (low boost) so we can compare them.

Hi Terry,

Ran map 1,2,4,5. Map 2 was the smoothest. I was surprised at map5, it was quite smooth too, but other runs were rougher. Ambient temp around 45-50F.

Lots of blue lights on the interstate, but managed to avoid them.

I appreciate your advice. I do have the EWG and FP wires installed.

Thank you all.

Bro i didnít see your calc_torque reading in your logs. Did you install the ewg wire correctly. Maybe someone from bms can clarify.

EWG wires look to be installed correctly.

Since you are running the EWG wires, best to run maps that make use of them, additive maps do not use the EWG wires.

Steve,

How can you tell the EWG wire is correctly installed, based on log info?

Thanks

Correct...EWG wires are only used on non-additive maps and can be seen on Calctq

What/where is Calctq?

Thank you for your patience with this newbie.

Default Map6 trial - 03-28-2018, 07:23 AM

Hi all,

I have set up map6 with and FOL of 75 and flat boost of 17.5.

It runs smoother than map 3 or map 5.

I would appreciate any suggestions.

Thanks

Alex

Not a particularly good log

Try lowering PID Gain to 8.

Flat 17.5psi is to much boost. Motor running to lean
Lower to flat 16psi

Thank you.

I have to agree with you. Just looking at some 16 psi runs
and they are nice.

Where would you suggest tweeking?

They look better.
Have you messed around with fooling IAt signal.
You can change it so you can get more timing.
6cyl timing set to 70

I was wondering about that. I am not sure how good it is for the run to have a stretch of zero advance. So setting 6 cyl to 70 gives more advance? Where did you see this?

There are so many “mystery” codes I never knew about ��

Also, the wgdc seems to max out a lot. I was thinking of raising the the FF setting to get better wg control.

Big help and much appreciated.

Alex

Hi all,

Should wgdc and ff be zeroed out? To me they should both be close together but above zero to permit room for adjustment.

Appreciate your ideas.

Thanks

Alex
