  1. Any base map to Direct injection? VAG?

    in G5

    Posted

    Thank you for the reply, the engine is the same that a VW GOLF MK5 BWA E113 engine.

    About the CANBUS, I don't have problem with it, because it don't has ABS, I want to put a Link dashboard and keypad etc.

    And with the fuel Pump, yes I need to know what hardware I need to drive it..

    Hi!! I have a KTM Xbow and I would like to start with it...

    But the injection configuration, is my limitations

    Are you working in some base map for DI engines in the next months? It will help to sell more units of this Voodoo ECU's.

     

    Thank you.

    I have done the stock ACD ECU and worked out a stragey on G4X to control Center differentials with 3 different maps for acceleration, and 3 maps for braking. Additionally, there is a slip and steering angle overlay. 
    Works quite good! 

    Interesting....waiting a explanation..please.

  4. Map limit count

    Hi 

    If I go in Ecu statistics, the MAP limit count increases every time I put ign on with engine not running. The map limit table is 2 bar above atmosphere all along the ECT range so it’s not actually reaching map limit. Could this be a software issue? 

    Yes, mine G4X appears all days the same...

    The new firmware has much improved gear shift functionality with closed loop shaft speed matching and limiting during blip etc but there are a lot of new settings so will need to be tuned from scratch after you update.  It is a good improvement though so is worth doing when you can.  Make sure you have plenty of time when you choose to update - dont update the night before a race day!

    I think in your log the actual gear cut is probably working correctly, but for some reason the logging rate is very slow so it has missed some of the shift detail.

    You would really need to use ECU logging and record at a much higher rate to get a true picture of what is going on.  I normally use 500Hz on RPM, Cut %, gear shift status, Gear barrel voltage and lever force when tuning gear shift.  

    In picture below, highlighted is the same shift that you have shown in your original picture.  Notice there is nearly 200ms between data points - this would easily miss the 118ms shift cut for 3rd gear.

    Ahhhh ok!!Adam, I will log faster and make more logs and When I can take some hours...I will update to the new firmware 

     

    Thank you!!!!

    If anyone has a source for the ECU Header Connector I might could help with a solution

    Let me know

    Jon

    I think the connector not a limit...a limit is to known all CANBUS messages to works with dashboard..clima..electro..etc etc..

    Do you  have this information?

  16. Driven Up Shift Ignition TRIM (absolute degree option??))

    in WishList

    Posted

    Good morning another one..

    IS possible to make like ANTILAG...the option of DEGREE ABSOLUTE or DEGREE TRIM.

    In somes tunes, the customer want to make pops and bang in desacceleration, and I make it retard the high rpm and low Load with retarded igntion, but...if the customer needs too CUT-off, I have much retard ignition retard for the reason of the sum of 2 "ignition trims".

    Then,...the possibily of put this ignition in ABSOLUTE DEGREE.

     

    Thank you.

  18. High fuel table value Modelled but low injector Duty

    in G4x

    Note as others have said above, in modeled mode the fuel table has nothing to do with injector PW or duty cycle, it is the volumetric efficiency, or in other words it is a measure of the air flow.   

    So if you have a value of 100% in the fuel table it means your 2320cc engine will inhale 2320cc of air in one engine cycle.  If you have a VE of 150% it means your 2320cc engine inhaled 3480cc of air in one cycle (obviously impossible).  

    Typically in modeled mode you will have a range of numbers from about 50-60% at idle to 100-120 at peak efficiency.  The areas in your VE table where the numbers are 20-40 is probably just because your injectors are working in the non-linear region and you dont have proper characterization data to correct it.  The areas where the VE is un-realistically high is possibly low fuel pressure or incorrect injector flow rate.   

    Yeah Adam, problem solved with my fuel pressure....now the fuel map (VE map) is better:

    YeeeeeahhH!!, is exacly, in idle are....my Inyector Dynamics 2150cc, are not very lineal.

    My head don´t understood that a 130% of fuel cell not correspond with more or less 80-90% of duty, now if I think in terms of VE efficiency I have understand all!.

     

    Thank you again Adam and the rest of the forum.

    Before considering what your injector duty is doing, consider what your fuel map looks like. Modelled mode is meant to model airflow based on VE. Your numbers in your VE table make no sense. I've yet to come across any engine that is only 20% efficient on idle, typically this value is around 50-70 depending on cams etc. 

     

    You have one of the following things going on:

    - Mechnical issue like bad fuel pressure, intake system leak, bad injectors, bad lambda sensor etc.

    - Tuning issue like: Incorrect injector data, engine data, charge temp correction, sensor calibrations etc. 

    Below is the variables that the ECU uses to calculate fuel delivery with modelled mode. Go through and check all settings. 

    In the past when I've had issues like yours its always either been a tuning error on my part or in some cases injectors were shit and didn't play well. 

    If all else fails put the ECU back into traditional fueling modeand give it a quick fuel map and see if your scaling is still weird. If it is then probably a mechnical issue.

    Yes, I have made another lancer EVO 8 with 1000cc injectors and G5-660 injectors, and at idle more or less is around 50-60 of fuel table, and a maximum of 100 of table "VE" for 85-88% of DUTY CICLE teorical.

    Checking the fuel pressure with a mechanical gauge would be a good place to start as mine was well out and htre my numbers out quite a bit

    Yes, this week I will take a fuel sensor pressure and view if my fuel pressure drop´s!

    To reply for the other guy, this is my G4+ NO MODELLED fuel (days ago). In both the calculated Duty is around 40%.

  22. Ignition Cut in Downshift?

    in G4x

    Posted

    24 minutes ago, Adamw said:

    Do you mean you want a cut after the blip?  Obviously there is no point cutting at the same time as the blip as you won’t get any torque/rpm increase.  

    There will be a more feature rich gear shift strategy with post blip rev matching etc in a future update but it is still quite a way off at the moment.

    Yes I have made an automatic blip when downshift with my manual gearbox to avoid push the gas...and I thought...the possibility of cut this autoblip to make a "pop" like the DSG or DCT at the change moment ..

     

    Thank you for your fast reply Adamw this product is the best in support. LINK THE BEST!!!jajaja

  24. Ignition Cut in Downshift?

    HellO!, 

     

    I am configurate the gear shift in upshift change, and the cars make the ignition cut like this:

     

     

    Then I need to make another ignition cut when I make the downshift ( I have DBW), I can Open the throttle body but I can´t made the ignition cut, is possible ignition cut?,

  25. Normalised knock

    in G4x

    Yeah, I was going to suggest you try setting learning rates to fast too.  I havent tried normalised knock mode with a low tooth count trigger wheel. 

    Also, I would try 13KHz narrow and 20deg window start, 50 deg length. - At least these values work best on my evo (not using normalised knock however as I last tuned it before that option was available). 

    Ok Adam, I will go faster and adjust this window´s parameters.,

     

    I have a due, I have installed an aftermaket bosch sensor in my 4G63, and for this reason I go to 6Khz (I have rebuild with 86mm of piston), 6.5Khz..more o less if I take the phormula.

    Do you think that is better 13khz with this sensor too?

     

    Thank you.
