Default How to get better timing? Map7 - 01-21-2018, 05:11 PM

Weird enough the same settings for the standard hex 8 file wouldnt drive without throttle closures. I downloaded hex 8 t12 and it runs map 7 with no closure but with fua at 30. My timing is low how do i increase it? Would reducing psi when meth kick in help?

How does map 1 and 2 look? Looks like you may not have enough octane.

How big is your meth nozzle? What is your base/in tank fuel?

Map 2 is not triggering meth, set meth trigger to 1. Otherwise the log looks pretty normal.

I would expect to see better timing on 93 but the B58 is also running very lean so cannot compare to N55. As Steve says try to run meth on map2 that should give a good boost in timing

Odd....there must be some sort of issue. Map 2 is an additive map and appears to be doing fine.

Have you verified your EWG wires are installed correctly? Your DME BT is all kinds of wonky and that is causing the JB4 targets to be as well.

Default Ewg wires - 01-25-2018, 10:30 AM

I also guessed that there maybe an issue with the ewg wires, however i tried map 6 and set everything to absolute boost and it worked. Map 7 used to work months ago but i have no idea why it doesnt now. I wouldnt mind running map 6 if its the same but the safety part scares me.

Have you tried setting FUD back to zero? That was where you had it previously. If that works then we can work our way backwards to see what went wrong.

Second log doesn't look so hot with FUA at 30, you'll need to experiment with that.

1st log as you noted does have excessive throttle closure but at least boost is smooth.

Default Close but no cigar - 01-26-2018, 08:25 PM

So im close.... or so i think lol.
I did a total of 3 map 7 runs but for some odd reason only 10 additive works fine once i changed it to 30 back to closures..... timing actually went up in one of the runs just want to add about 2-3 more pounds of boost and keep the timing the same and afr the same and im happy. Any suggestions? Ff was adjusting all over the place idk if thats good or bad.

Add 10, FUA 15 looked good. Can you slowly start walking your adder up? FF will adjust as needed but we need to make sure it's not too high. Better for it to learn up than down.

So im slowly walking the adder up like 5 add evey trip to and from work and its slowly working which i dont understand why it wasnt working before with the same additive. Is it because it has to slowly adapt? And if so whats it adapting so far im at 25 add and its going good.

Nvm it still doesnt go past 10 well ... 20 breaks up throttle again. I even tried map 3 and it breaks up with 40 add but map 2 doesnt. Does this hint for something?

That is odd...the additive doesn't affect map 3, that is only for map 7. Does map 3 exhibit the same issue if meth is disabled?

No only when meth is enabled. I can give logs in about 3 hours if needed.

You set your FUA back to 0. :

I would eliminate meth for now and get it stable at lower boost settings. Then re-introduce meth.

Looks much better when you are underboosting but still pretty lean.

I haven't had to play much with that as our car doesn't have those issues.

This engine is extremely sensitive to tuning and hardware changes. Adding meth can help AFR, but does not get you completely out of the woods in all areas.

I have noticed that DME BT needs to be above 12 or so for Map 7 to be working well. It also cannot be fluctuating too much at any given time (up or down).

Actual Boost needs to be within about 1.0 PSI of JB4 Target, otherwise FF is too low and I start having issues with DME BT, which hurts AFR (too lean) and timing (too low). This is true when running a meth or non-meth map.

When I run Map 6 (without meth), I have issues whenever I target anything less than 16-17 PSI. DME BT just doesn't like it. I don't even attempt additive maps with MPPSK because it runs so bad in all scenarios.

DME BT is the biggest factor in a good log on the B58. If that is not running well, AFR, timing, and other stuff WILL suffer.

So.... strangely i switched back from x98 to M1 (meth) 3 days ago and the my car runs smoother. It started to rain so i didnt get to get a great log, and its been raining for the past few days but tomorrow ill try and get a map 7 with meth log as well as a flat 17 for map 6 which i wasnt able to do once i switched to x98 i had psi highs of 12 for about 3 months. I started to backtrack track dates to see when it worked and when it didnt and it seemed to be right after i switched to x98. i appreciate you updating me though with meth the dme seemed to be much happier idk if its a random act or it actually is better for my car.

So your saying i should increase my ff if i see that my actual is below my target?
Whats a good tip to keep dme bt up?
When key elements is there in a log to see if i should add more octane like e85?
Also whats a good rule when trying to balance fua and additive? As i increase add i have to increase fua it seems but i havent tried it with meth. I also realized low add and low fua felt better than high add and high fua.
Thanks again
