Hey Russell,
I noticed the N55 EWG cars run leaner than the pneumatic solenoid cars - do you know the reason? Could you also update the front page to show what AFRs to look out for so us EWG can have a better idea when looking at logs?

I believe the OEM DME's on newer cars are staying lean over a wider power band to help mileage..... but just a guess. Staying under 15:1 after tip in mid power band is starting to be the norm. If it was really too lean it would knock or miss. DI is a different world. JMHO

Yes the probe is a wideband sensor and reads lamda. Most cars run gasoline so lamda is multiplied by 14.7 to get AFR. Cars running 100% E85 are not running anything near 13:1 AFR @ WOT but for the sake of consistent indication..... that is what is displayed. No correction is being applied for fuel mix.

that makes perfect sense especially the bit about ethanol and fuel mix , i was wondering how the jb4 and factory ecu was converting on the fly for different fuel grades. cheers

So does that mean the ECU reading E35 is not really the correct E35 AFR? If so, how can we determine the actual AFR for safety?

Goggle Lamda and AFR.
There are many good articles on the subject, however, it is a little too involved to explain here in a few sentences.
You will have to trust me when I say that the AFR readings in the 12 to 15 range typically seen here (irregardless of type of fuel) are safe on any fuel mix........ but are only 100% correct when running on 100% gasoline.

I assume you are running a BMS supplied meth system. Your "Meth Flow Scaling" value should be set to 60. Yours is set at 45???

Are you running with a single meth nozzle or multiple nozzles?
I am seeing a 21 degree drop in IAT so you are spraying something.
Has the current meth system ever indicated 100 flow in the past?

Your Map 6 is very aggressive since you are raising boost setpoint continuously as RPM rises over the whole rpm range.
Also your Avg Ign value is not staying below 1.5.
You had a knock event at max rpm and boost..... which is not good.

Hey Russell,
For some reason my JB4 changed from AutoShiftDamper 15 to 0 on its own. Do you know why it would do this and what this is for? I have an N55+EWG car.

Auto Shift Damper adjusts the amount of PWM reduction during upshifts with cars with automatic transmissions.
I have no idea how your value got changed.

Should I just put it back to 15 for the F-chassis?

I want to experiment with E85 mixtures, but wanted to see where in the logs I can monitor my FP_H Levels? I do not see it on the graph, but see it in the program. I know if it goes below 11, then that's where its basically maxed out...but I want to know where I need to be looking to monitor this. Thanks.

I need a little help. I seem to be maxing out at about 14.5-15psi boost on map 5. If I bumped up the boost values a pound or two in the user settings would that actually raise my boost? I am currently running JB4 g5 iso,VRSF *********, ER chargepipe Tial blow off valve, BMS dual cone intakes,Cyba scoops and 35% e85.
