Which pull up are we interested in? Temp Ignition or Di?

If you could also put up the MAP (.PCL) file from the ecu as well so we can see the tuning information.

Hi Peter. Would you be able to take a screenshot of the lambda / quicktune issue. Same would be good for the vnet/dash configuration. If you wanted to send the units to us we can sort on the bench.

If it's a wire in unit you just need to connect the serial interface to the ecu. I'm assuming the adapter is wired to suit? If it just has a serial plug then you need a CANSER cable which goes from ecu to 9pin D serial.

Hi Dave First are to look at will be what the Idle duty cycle is doing. Given you have the AC step at 0 the duty cycle should stay consistent and not increase when the clutch turns on. If you find that the duty cycle does increase we will need to get your map to try on the bench. If however it stays the same or even drops a bit as it tries to pull the idle back then we need to look for other sources of air getting into the engine.

Hi Neville Unfortunately not on the G4. On the + series we introduced the option of OBD output.

Yep same story for the V88 and yes the map can be converted over. All you need is the New ECU online and then open the V series file and it will load to the ECU. New features will of course need to be set and checked.

Yes you should get an improvement. With the temp up at 500 there would have been no cold start fuelling at all until there was some temp in the engine.

Hi Craig If the temp came right once there was some heat then its likely a firmware issue where the temp calculation has overflowed causing it to read at the other end of its scale. No real fix for this other than a upgrade to later firmware which would require a retune and ECU back to us for a V5 upgrade.

Hi To use the software you need one of our ECUs fitted it is not geared to work with factory or other aftermarket systems

On V series this is not an option all readings are in metric. The later I Series offer the option for psi.

Hi Thanks for the MAP Have you tried in group fire mode for the fuel? Will the engine idle and free rev? And only miss under load? Or will it not start?

What happens if you set the ECU to group fire mode? Can you post the MAP so I can run on the bench. However the only way the ECU can read a high RPM is if there are signals to make it think the engine is going that fast.

This indicates trigger errors. This could be due to incorrect configuration of the triggers or electrical noise on the trigger inputs causing a false RPM reading.

Hi Motionper I assume you have added a sync signal to enable the sequential and prior the engine was running happy on just a crank trigger? If this is the case you need to look at the configuration / wiring of the sync signal.

On the G4 there is no way to have the readings in Fahrenheit. This is a function that has been added to the G4+ range Any of the sensors listed in the drop down are pre calibrated. If doing a custom cal the figures will have to be adjusted to match the sensor.

Yep you can mix and match to you hearts content.

It will really come down to what suits in terms of size and ease of fitment. Subaru, GM, Ford, Nissan have all be used with success.

Yes is the short answer. The limitation on the Atom is the number of inputs and outputs. So for this application you will likely be using the following outputs. Ign 1-4 Ignition Inj 1-4 Fuel Aux 1 - Fuel Pump Aux2 - Engine Fan Aux 3 - Tacho Aux 4 - Boost Control If there are extra items you want to control then you have run out of outputs and might need to consider one of the other units.

Hi Crispin Can you post up the map so we can drop it into a bench ECU.

Hi Looking at that file you have a V44 plugin so have moved topic to the V series forum. It is also running very old firmware so it would be worth considering an upgrade to the firmware as there will be a number of new features and bug fixes. There were a number of changes to the Anti-Lag too. However looking at the Lag settings I can see you are running mode 2. This is a GpN mode and is expecting the throttle to be held open. As such the cyclic cut will always be active. Mode 1 might be a better match for your application.

Yep the plugin only has the one output configure and is intended for parallel twins or a single conversion. This is the same on the rotary plugins too.

Yes with G4 firmware you can. The other option is to upgrade the internal sensor to a 7bar one.

Check the polarity of the crank sensor. and also the arming voltages. Sounds like you have some trigger issues at that RPM.

On G3 firmware this is not an option on the LEM you have to use the internal sensor.
