  1. Use a second E Throttle Target table Use a combination or a Launch Switch a Virtual Aux and a Timer.
  2. Don't mess about with other types of wideband just fit a CAN Lambda, it works perfectly does not need calibrating and once tuned you can have it in Closed Loop mode and have perfect fuelling resulting in great economy.
  3. This is not a damper issue I fit FP Sensors to every install and don't think any of them have had dampers fitted and I don't see fluctuations like that, + - 10kpa maybe If your fuel req is vacuum referenced then I would log 'differential fuel pressure' instead and that should be steadier. Differential fuel pressure is a calculated value derived from both MAP and FP.
  4. We have seen the same issue and it worked with the CAN unplugged.
  5. It’s used on any engines when MAP becomes an issue, using TPS as you load axis will give you demand based fuelling and not reactionary based fuelling (your throttle input is the demand and MAP is a reaction) MGP on the load axis is great for slow revving car engines with high reciprocating mass but for jet skis I would always go TPS.
  6. I thought so, I think you will find retuning with TPS as the load site on the fuel map will make it a lot better.
  7. I am afraid my best advice is to retune using TPS instead of MAP on the load axis of your fuel table. Is the motor boosted, seems the map is configured for a boosted engine ?
  8. We have done over 60 Cosworth installs and have a superb map that will only need a tweak on the dyno for your car saving a lot of cost in dyno and mapper time, however we like to fully support our customers, if you purchased the ECU from us online the base map and full technical support including a team viewer session is available free of charge. If not we have a support product you can purchase, you are more than welcome to ring and talk to us about this and make sure you are happy with what we offer, 01474 853219 https://shopbhp.com/collections/link-ecu-accessories/products/link-g4-ecu-support-base-map-service
  9. Out of interest did you have anything connected to the CAN port ?
  10. The Lambda trace actually isn't in the correct position as the reading lags so I would say its going lean on a throttle blip, best way to see by how much the Lambda is lagging is to set a switch on a DI and when selected add 10% to the fuel map, hold it at 4k rpm and switch the DI on, by logging the DI and the Lambda you will see how long the lag is, you can then read the log better. I would say if the fuel table is correct then you need to adjust the accell Enrichment. Logging TPS delta along with the TPS trace will help you work out whats going on. Hope this helps.
  11. Upload the pclr file and a log and we can take a look.

    Question

    The map is preloaded.
  13. No they are not presented on the ECU connector unfortunately.
  14. Should be no need to change maps if the vehicle is the same. Do a complete system check before you run, so check every sensor and actuator works. The only thing that may need wiring is the second air temp sensor.
  15. Wire IGN1 to Coil 1&5 and IGN2 to coil 2&4 and IGN3 to coil 3&6 - the firing order in the configuration tab will tell the ECU which coil to fire. Ground from the Coil can be bound hard to the head / block the ECU does not look for a return signal.

    Question

    Fuel pumps look fine, just check the fuse is man enough. Everything still applies in 6.7 plug in or not we always test ever sensor and actuator.
  17. We have our early AE86 Electronic dash working by just bridging the input resistor with one of the same value.
  18. In the Aux Output you can find the valve setup.
  19. You can see the Lambda's temperature in PCLink you just cant use it as a variable.
  20. The fuel and ignition does not have any checks in it for types of triggers selected - very common. Also very common for the ECU to default into batched/banked mode in the event of Can sync failure, it’s a good strategy as it allows the e give to run on the first turn instead of waiting for 2 revolutions before starting.
  21. No it still needs a cam sync for this as you get a missing tooth every 360 degrees in the 720 cycle.

    E-throttle wiring

    You can indeed, you just need an aux out assigned for it to work, the down side of not having the relay is a bit of safety.
  23. As a general rule the peak current will be around 60% of the total draw in current found in ohms law, this is because we are not actually dealing with resistance but magnetec inductance and the solenoid coil will start making maximum magnetism well before coil saturation however the only way to really tell is to watch it with an oscilloscope. So in your case at 14v the current drawn in ohms law would be 5A like you said so 60% of that will be 3A and the hold current will be 25% of that figure 0.75A and the requirement will rise slightly as fuel pressure rises. So I would try 3A and 0.75A
