Reading Outlaw's post has me drooling at the JB4 with the g5 board.Mine has been shipped last week Wednesday and should be here soon :joy: With the previous software that I had on my car,I hardly encountered anyone on the road for a "quicky" but as "Murphy's Law" would have it now that my car is standard,every Tom,Dick and Harry wants to have a go at me on a daily basis:argh:

Like they say in afrikaans,"My stert jik",very soon all will be well.I can't wait,gotta luv the boost:joy:

:roflol:

isnt that the truth. its uncanny how they know when the tune is removed??? it puzzles me too.

Haha...same happened to me tonight. Just collected the car from ART. Car is complete stock (everything...including exhaust...except for the wing of course. Its last service for the year is tomorrow.

C63 on my tail...on the N1. Did not even notice it. My brother is driving on my left and i am in the right lane and a slow car infront driving 120s. My brother see me wanting to pass the car on the left and give way...C63 followed hard on my tail...as i push through the gears i make small gains (half a car) at about 220s i slowed down and the monster flew pass...A stock 335 drives like shit...sorry stock guys.

Next time...:thumbs:

Forgot to mention before my wagon went in for turbo no 2 i tested the G5 Board with the new Firmware and updated software is awesome! Just dont forget to set Bogfix on 100 when not using launch control or NLS!!!:rollsmile:

Getting my wagon next week, removed entire system plumbing and everything and make sure system is free of debris as we have now installed 2 brand new dryers and some other goodies.

TWINZ :

Please can you give me guidance as to the following :

For the G5 board, is there a specific setting for the 1M based on the engine and tune it already has. If so can you please email me the settings.

Once my G5 board arrives i will send you logs to fine tune however as i am not so glued up in rrespect of AFR adjustments.

I have been searching on other forums but no real inforamtion.

G5 board has specific 1M settings and is a option tab you tick or select a and you done that's it as easy as that. Download G4 latest software file under G4 board sticky which then has several options of car types under settings abd tick 1M G5 option and then download latest firmware off the G5 board sticky I think it's 0916hex file or something.


Twinz glad got both files anyways.

That's just a default page of what you must set everything to after loading the new firmware and software versions also on the site.

Hi byby...We will assist you with the install and logging once your G5 arrive. If you look on the second page on this thread where the G5 information is contained you will see right at the bottom is the G5 default settings. These are the same for the normal N54 & 1M.

Also let me know if you manual or auto.

My suggestion is that you and edz consider the BMs backend flash since you planning to mod the car fully. The flash separates the fueling control from the JB and does away with the need for cps & e85 wiring etc...Ideal for bigger turbos, Meth, e85 and nitrous applications. It also allows you to run much higher percentage e85 fuel mixes. Additional wiring will aslo be available soon for the isolated boost control settings; which brings the JB inline with what is currently being offered by other piggys & flashtunes such as Cobb etc...

Got my Wagon back today with new dryers and suspension setup. All is well with wagon1 and G5 is unbelievable with adaption on new hardware. All other FBO's are sorted and the car is pulling stronger than ever, will dyno in next week to see what gains there have been made and will post on my build thread. :inlove:

That log is way off.
Something is not right. AFRs are scary lean and you not hitting boost targets. Fuel trims look fine but need to see more details. Would have been good to see a full completed run hitting 7000rpms.

Anyway once I have the detailed log we can go through it off-line or via email. I am sure we can get it sorted
