  1. You can use MAP or MGP for the ignition table. MGP will adjust the timing a little based on the values in your ignition table. Ray.

    The open loop AFR table needs feedback from a MAP sensor. The axis can be MAP or MGP. Using TPS will mean this table will not work correctly. I do not understand why you have the Fuel table as MGP and the ignition table as TPS. The other way around, or both TPS I could understand. TPS should be used for the fuel table axis is when the engine has very big overlap cams, or the engine has individual throttle butterflies and turbocharged. In cases like this these are the settings to use, Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = TPS Ignition table Y axis = MAP AFR table Y axis = MAP There will be no baro correction, but tuning will be easier and the the AFR at various manifold pressure with the same TPS setting will be correct. This method of mapping is very powerful, and what makes the Vipec stand out from other make ECU. If you map the engine using TPS only, or do not setup this way, you may as well use some lesser ECU. Engines with one throttle butterfly or mild cams should use, Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = MAP Ignition table Y axis = MAP AFR table Y axis = MAP or if you want baro correction. Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = MGP Ignition table Y axis = MAP AFR table Y axis = MGP If mapping using TPS only, then you may as well be using a carburetor as it will do a better job of getting the AFR correct. Any engine tuned at sea level with these settings, Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = MAP Ignition table Y axis = MAP AFR table Y axis = MAP can turn on baro correction by just changing AFR table Y axis = MAP to AFR table Y axis = MGP. Just make sure the MGP axis values match the equivalent in MAP.

    ECT temp issue

    Yes I still have it. I could never find anything wrong with the ECU. I am 99.99% sure that what every your problem, it is not related to one northwestsupra has.

    Mark, You are using TPS for both fuel and ignition. You should always use a map sensor. If you want to use TPS for fuel mapping then use these settings. There will be no baro correction, but at least the engine will be easier the tune and the tune will be repeatable at all engine loads. Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = TPS Ignition table Y axis = MAP AFR table Y axis = MAP. If you want baro correction with TPS mapping then use Fuel Equation Load=BAP AFR Table = Off Fuel table Y axis = TPS Ignition table Y axis = MAP

    I will get you an answer on Monday. I recommend you use the ECU logger. This will log at the correct rate at all times and is not effected by noise on the USB cable. Ray.
  7. The zero rpm and 500 rpm values are critical for starting. Use what is in the help. They are know to be correct and many engines are using them. Ray.
  8. 1. Turn off the 4D table and turn on the IAT Fuel correction table. Select MGP for Y axis of Open Loop AFR table. Turn off the Ignition table 2, as the values in this table cannot suit any engine. Turn off the 5D ignition table, no values in the table so it not being used. Change Trigger 2 filter level to 2. Retune the engine before running it again. 2. The open loop table is a lookup table used by the ECU to know the air fuel ratios the engine should run. This table is open loop and does not require any narrow or wideband 02 sensor signal. The ECU uses math to know how to correct the air fuel ratio. If you search on this forum will find this discussed many times. 3. If the whole fuel table is tuned, the tune will be correct no matter what boost you run. No 02 sensor is needed to correct for more boost as your tuner would have tuned for higher boost. 4. Your ECU is a marine version. It is full of epoxy and cannot be pulled apart to do the modification for CAN. 5. I will send Jim the table settings. 6. You should not need to use Closed Loop Wideband if the engine is tuned correctly. To set it up CLC Wideband, the tuner needs to find the best settings for your engine. Ray.
  9. After a lot of looking at maps and data logs, and discussions with the engineers I have an answer. I was never told by the engineers the way the baro correction works when you have the Open loop AFR table enabled. Because of this the baro correction is not working correctly on your engines. I have told Jim the setup for baro correction is this... Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = MGP Ignition table Y axis = MAP AFR table Y axis = MAP. When it must be.... Fuel Equation Load=MAP AFR Table = On Fuel table Y axis = MGP Ignition table Y axis = MAP AFR table Y axis = MGP. The difference is the AFR table Y axis is MGP rather then MAP. I said in the past there was no IAT fuel correction in the maps. I was wrong, you are using the 4D table for this. It would be less confusing if you just used the IAT Fuel correction. This is located under Fuel -> Fuel Corrections -> IAT Fuel Correction. I have sample settings for this table if you need them. So what this means is the engines need to be re-tuned so you have one map that suits all altitudes. I am sorry about this. Ray.

  11. All the tirgger settings for this engine are in the software help. Help -> Contents -> Engine Specific Information -> Subaru -> Subaru WRX/STi V10. Set them exactly the same and see what you get. Ray.
  12. Can you send the email again. I cannot find it. info@vi-pec.com

    A common cause of flat spots is too rich and not too lean. When I look at your fuel table it has very big numbers at the launch rpm and load. This could be the cause, but I suspect you made these number big, trying to fix the flat spot. If so... that is not how you adjust acceleration enrichment. There is two dedicated tables for acceleration enrichment. These are the Accel Load Correction and the Accel. I have modified your accel settings and tried to guess what the original tuned cells on the fuel table were set too. Ray.

  15. V44 can be used on cars with DBW throttle. You need the external DBW controller. This uses a few inputs and outputs on the ECU so you could not have enough on a engine with dual VVT-i cams. Ray.
  16. New tables are only created while online to the ECU. Once created they will allways be there. Ray.
  17. Try selecting Ford Duratec. This engine has 36-1 on the crank and a similar cam trigger wheel. If the engine runs, then we will add support for the other cam. Ray.
  18. Only one device can be connected to the USB or RS232 ports. You cannot have dash on one and PC on the other. If you use the CAN connection on the AIM dash rather then RS232, you can have the dash and the PC connected at the same time. To use the CAN the ECU will need to have a serial number above 10000 or have it sent to a dealer to be modified. Ray.
  19. If you have a marine ECU it must be set to marine. If not then standard. Marine ECU are very heavy and have a port on the connector end of the case for the baro sensor. Ray.

    No it does not do this. Please send me the data log. info@vi-pec.com
  21. You cannot have the AIM dash and the PC connected at the same time. The AIM dash has to be disconnected at the ECU end of the cable and not at the dash end. If you leave the cable connected to the ECU, you will have software communications problems. Ray.

    I have the base map, but not one to suit your modifications. If you want the base map, send me and email. info@vi-pec.com Ray.
  23. There are two GP RPM Limits. Both are under Limits in the Settings menu. Ray.
  24. I know the Suzuki Hayabusa has a stepper motor with a feed back pot and is closed loop controlled. If it only needs two positions, then it can be controlled with two Aux outputs. Use two of these outputs. Aux 5,6,6,8. Set them up so they have different polarity, and opposite switch conditions.

    Do you have a datalog showing this happening. Ray.
