Default Jb4 reverts to Map4 - 08-02-2018, 06:52 AM

Started a thread few weeks ago with JB4 throwing CEL and codes about cylinder 6 misfire, got the coils and sparkplugs changed. Now I get thrown into reduced power/Map4 without any codes. First 2 logs are with 33% E85 mix and the last ones with 50/50 mix. Map 7 is totally useless at the moment, I get instantly thrown into Map4 when flooring it, probably due to overboost.

Mods are: JB4, VRSF ******* ***, VRSF upgraded intercooler, chargepipe, TBI kit, fuel-it stage 2 lpfp.

Under read only settings check last safety.
You are probably getting something in there like lean or fuel pressure etc

Last log you are overboosting, which is why you are being thrown into map 4.

Set all your DB to 50, and relog.

FF is maxed out- manually lower that to 70

Enable cyl timing too

Got rid of getting dumped to map4 and the car is pulling somewhat strongly now.

Couple of more logs with Map7 and ~45% ethanol mix, it was very hot today and these were probably not the fastest pulls. Went earlier today with an -10 RS3 which was tuned to 400 hp according to the owner, very even until 60 mp/h after i started to pull away somewhat easily.

Made the configurations and also upped boost safety to 21, dont know whether that is wise tho..

Any suggestions for refinements? Im also thinking of upping the ethanol load to around 60-70%, that is perhaps the best ratio or so Ive heard.. I want to go faster I was surprised how the RS3 kept up until around 60-70 mp/h, ok he was tuned as well but still, wanna whoop his ass brutally :D

You need to update your JB4 firmware.

Also are you in menu 4/2? If not, that should be used with the BEF.

Odd you arenít getting all your cyl timing values either.

IF you dont mind me having a peak as a noob,
I saw the log, and i can confirm that the Boost Safety increase from 18 to 21psi was the correct call, as the N54 TMAP sensor limits at 21psi from what i have read (If you want to chase more boost, get yourself a N20 TMAP sensor, and amend the setting in JB4. this will increase your boost ceiling.

I agree with Dave, your 6cyl timing is not showing, neither is your VIN number, can you confirm year model, perhaps you have the incorrect DME model (I8E0S/IJE0S).
AvgIgn looks really good, im jealous, you running Meth?
