  1. upreving with TPS 0%

    in Vi-PEC i Series

    My thought would be the same as yours - with supercharger, pipework, intercooler all before the throttle, you probably have 10 litres or more of "plenum" volume that the engine has to evacuate when the throttle closes. 

    Ideally you would move the throttle blade to a more appropriate location, but thinking outside of the box - you could possibly use cyclic idle to stop the "flare up". 

    Sounds a good idea.

  2. upreving with TPS 0%

    in Vi-PEC i Series

    Hi,

    my car is a twincharger. air root is filter>turbo>W2A intercooler 1>throttle body>supercharger>W2A intercooler 2> engine.

    My problem is that when I have TPS wide open with low rpm and then close TPS and push clutch at same time, engine continues upreving for some miliseconds. I'm using fuel cut. It seems that it takes some milliseconds till full vacuum so map sensor reads some air in the piping because TB is a bit away from the inlet.

    Is there any solution?

     

    Thanks

  4. aem 5 bar map sensor

    in Vi-PEC i Series

    Posted

    Hi, could you please inform me what are the calibration prices for table 4,5,6 for aem 5 bar sensor? is it input value A=0.5 v for output value A=0 kpa and input value B=4.5v for output value B=416kpa?

    Does the link 5bar predifened map sensor has the same values outputs so I can select this from map sensor's drop menu?

     

    Thanks

    It will solve the problem partially!!!!Actually the combination of using the virtual aux conditioning can give up to double conditioning capabilities. Its nice to play with conditions LOGIC especially for complex projects, this is also make a good STANDALONE ECU different from others, this is also a good reason for people to buy a good ecu vs a cheap, you know better than me that conditons makes the aux outputs double effective for the tuner. The more they are the best for the tuner.

    Thanks

    So it seems that I will have same thoughts if i go on with Thunder, as for the conditioning streams. In the past while I was playing with g4+storm I have spoken with several people here, they all would like this update and they maybe post here. This was actually the reason I have upgraded to i88, thinking it has more 3 conditioning outputs. I shall wait for release of new firmware update. Thanks again.

    Simon: I actually need the conditioning to control engine sensors and solenoids, the autmatic gearbox swap is not my priority, it a quite complex twincharger project (turbo and supercharger compressor combination) so I need condition. It could be very easy to add the extra conditioning strings in the firmware

    Scott: For sure I could do this but I also need conditioning for other solenoids that I havent already connected, so I planned to move what you reffered to use thes ouputs for other usage. It would be nice if you could add the strings to the firmware if the harware could support this. It would be also nice if you could update the firmware to use also virtual aux 2 and 3 in the conditioning, I tried to use virtual 2-3 but they dont seem to be available in the list.

    I also want to control the electric power steering....so many I/o ports are needing...

    Do you think that I have to upgrade to Thunder? Does thunder has more outputs with full conditioning abilities. Actually I have started with g4+ storm, the upgrade to i88 and keep the g4+ storm unused for another project because of the i/o ports were very few, so I wouldn't like to upgrade again to another ecu and spend such an ammount of money.

     

    It would be nice if you could add the strings...It would solve my hand.Fingers crossed.

     

    Thanks.

    I'm running i88 and I'm on the way to convert to auto gearbox.

    The auto gearbox ecu receive 4 signal named idl, L1, L2, L3. The idl comes directly from tps sensor when there is no tps open angle to the gearbox ecu 0-12v, the other three signals are converting by engines ecu to 8 delta% tps openings. the the L1, L2, L3 are 0-5v signals outputs from oem engines ecu that are driving into gearboxes ecu for gear changing. I have attached the pdf of the gearbox logic and sensors to take an idea how it works. Go to page 4 to read accuratly my description.

    The question is: how can I drive these signals?

    Another simplethings that works 100% is to use the oem's coil primary terminals. The connection is simple. + coil terminal connected to an IG+, - coil terminal connected to tachometer cable (as it was when OEM ecu was used) and tacho output from ecu connected to the coils edge - with a 0.33 kohm resistor. Same like the image that AdamW posted but in case of the relay coil we use the oem's coil primary terminals. Work 100% and also triggers the A/C OEM computer.

    Another question is: The oem ac computer receives the same signal as tacho in order to see that engine runs and activate the compressor clutch. With this modification the ac ecu does not activate the clutch. Is there any possibily the current isnt enough strong to trigger the ac computer? fingers crossed...

    Ok I have made this work with the haltech diagram but with 0.33 kohm resistor. Is it a problem for the ecu safe?Shall I add a diode to protect the ecu output from over back current?

    I have disconnected the lamp from the output. With the cable in the air, when I enable this port, the code 73 appers. At runtime values the voltagr of the 9/10 port drops to 4.5 when I enable.

    Hi,

     

    Can I drive on aux 9/10 a CE light? I have connected Check engine light on aux 9 and ecu fault 73 appears? and check engine flashes?If I energise this output like a gp output then no fault appears. What maybe the problem?

  24. 180 degrees spark

    in G4+

    Posted

    Hi,

     

    how can I turn 180 degres the spark? I have spark at 4 when need spark to 1, spark at 3 when i need 2, 2 when I need 3 and 1 when i need to 4. Do I have to simple change the firing order from1342 to 4213?

     

    Thanks
