My Wish List

1. How about allowing the injector battery comp table to have an 'X' axis. When a rising rate regulator is used the injector dead times can be adjusted based on fuel pressure. 2. Allow the 4d and 5d tables to accept larger values. A good example would be if TPS is used on the main fuel table, Baro and Map can use the 4d and 5d tables. I use an alcohol sensor for alcohol content in my fuel when I mix it and cant spare my Dual Fuel Table. Yes I know that MGP can be used for baro comp on the main table but idle quality is poor because of the cam and fueling suffers at idle. 3. Needs MORE CAL TABLES! OR give us a way to store Calibrations to the ecu similar to the installed ones for user selectable sensors. 4. Configure Fault Settings to allow for other input thresholds to be used to trigger the CE Light. 5. Timers! 6. DBW trim tables to adjust the throttle translation table. This way as engine temp increases or boost pressure increases (just two examples) you can close the throttle. 7. More CELLS for the CAL Tables to allow for more definition of non-linear sensors. Thanks, Rob

Hi Rob,

1. At this stage this feature is not avaliable and probably won't be in the near future.

2. No solution to this problem sorry.

3. There are 6 calibration tables on the G4 ECU, have you used these all up?

4. CE light functionality has been upgraded, and will be avaliable in the next firmware release.

5. Yes they would be nice, but they are currently low down on the priority list. Using a switch connected to a DI is probably your best bet for now.

6. DBW firmware is still in preproduction and has not been finalised. There are many more DBW feautres to be added.

7. We believe there is enough accuracy in the calibration tables for most situations, these will not be changed in the near future.

Regards, Phil

Generally there should be no need to use Baro on a overlay or correction factor as baro will always have a effect if the correct fuel equation is used  if using TPS as main fuel load axis then baro should be selected as the fuel equation

Dave, My setup should use Load=BAP/MAP XOver, its a turbo motor at 28psi. The problem im running into is that at altitude its not compensating (the baro does show the correct pressure compared to my weather station). Im currently using Load=MAP but the motors idle quality is poor and selecting "Map" or "MGP" as the 'y' axis results in very poor idle fueling. Plus making manual trims to the fuel table is not the best and your always chasing the weather. What I've done in the past using Motec ecu's was TPS on the Main fuel table as the 'y' axis. and used a baro comp and a map comp to make altitude and boost pressure fuel changes. This has worked very well for me. I also run an alcohol sensor in the fuel system and measure my alcohol content in the fuel. This allows me to run race gas or alcohol or a mixture of either and not have to re-trim the fuel table or send a new config to the ecu. Since the 4d & 5d tables do not allow a value greater than 60 (I belive, been a while), I cant do a Map comp using those tables. For example for the Map: MAP KPA | 0 100 200 300 400 500 Fuel Trim % | -100 0 100 200 300 400 These values are not allowed. How have you used the Load=BAP/MAP XOver fueling equation? Has anyone else ran into the 4d and 5d table values as being an issue? Would it be possible to add two tables to the software for dedicated Baro and Map trim tables or allow the 4d and 5d tables to accept values greater than 60? The help file says: The best way to use this mode is to span the main fuel table using TPS. Enable the 4D fuel table and span its Y axis using MGP. Set the Y Axis to start at 100 and ensure that all numbers in the first row are 0. This gives BAP correction over the entire operating range and allows fuel trimming under boost. But you cant enter a value that high ( cell value must be between -60 and +60 ). So does that mean this table is scaled? I would love to see someones config that was successfully using this method. Or even a startup config used for new setups using Load=BAP/MAP. Thanks, Rob

Hi Robert

can you send me your current pcl file as it will be easier to explain if i can see how you have it set up

if using tps as main table then you should only be using BAP as the equation not BAP/Map X over especially if you  are seeing a large change in mixtures with altitude

Hang on you keep refering to load=   are you on a G3 or G4 and if it is G3 what firmware?

Dave, The ecu is a G4 extreme, latest firmware. If Bap is selected as the fueling equation... how will it compensate for boost pressure? I will send you a config, should I send it to info@dtechmotorsport.com? In the mean time can you send me a generic config that uses Bap/Map xover? I would love to see how Map and Bap are setup. I dont see how this method can be used for my application where tps has been selected for the 'y' axis on the main fuel table. Thanks, Rob bravo685@gmail.com

send it to the info@dtechmotorsport.com address

use bap as the Fuel Equation this is the important part

use tps as Y axis  this will take care of the idle vacc instability and have baro correction on the main pulse width

Use map as the overlay table this will take care of the boost areas of the tune

 

or you could just use Map as fuel equation  set Y axis as MGP then use TPS as the overlay  to correct for the idle issues     depends on your tuning style and severity of  the idle issues

Hi Rob,

Just thought i'd let you know that the latest G4 Firmware not only has the CE Fault codes working but also adds 3D table option for Injector Deadtimes, just right click and 'Axis Setup' and you can add your Fuel Pressure 'AnVolt' as an Axis.

What sensors are you using that are taking up your Cal tables? Don't forget that you can use one Cal Table for multiple sensors (If their Cal's are the same).
