Long term yes, But its not a mission critical one currently so have no idea when it will be looked at again.

unfortunately no way to use out puts as inputs. If all an volt channels are full only option will be through CAN

We had a few units slip through with the USB chip programmed incorrectly. That is a suppressor to go between the 12V feed to the coils and ground. Helps to keep the 12V clean.

I assume you mean Analogue inputs to log a voltage? If so one option is to use a E888 on can, this will give you 8 additional AN volts to work with. They will only be able to be logged with PC not internal logging.

For sensor inputs its in absolute so 0kpa is in this case -15psi and 30psi is equivalent to 300Kpa http://www.linkecu.com/support/documentation/technical-drawings/G08

To check the Fuel pump / AC connections you will need to use the test function on each aux out to check which is which. For the stepper are you able to post the map as you have it set.

I think your issue will be the settings on trigger 2 As you do not have a cam sync the sync mode in trigger 2 needs to be set as none.

On your wideband is the AFR reading correct on the volt input?

Hi Which board revision do you have 1.1 or 1.2 and is it running the V88 or V44 top-board? There is a note on the pinout information that on some applications the AC and fuel pump are reversed in location. Is the stepper moving when it is doing the reset at key off? It should wind to fully open and then reset to base position.

With each having their own supply 1.5 would be more than enough. You are correct in allowing about 10amps per coil.

Might be a bit of a combo of both. What are you using in the way of triggers? If its multi tooth crank with a sync on cam it would be worth checking the can sync is not occurring at the same point as a trigger on the crank. And if its multi tooth missing on crank with a single tooth sync sync make sure the cam tooth is not on top of the tooth after the gap. I would also try going back to the old leads to see if it has any effect.

Are you still running the RB26 intake with 6 butterflies? If so you best bet will be to tune using TPS for your main table and use a MGP overlay table. This way at light throttle you can have lean mixtures but still maintain good mixtures under higher loads. This can be achieved as you are not going to be in the same load areas in the tables. The accel fuelling will compensate as you transition through the table.

Being a distributor ignition system will allow you to use just two teeth on the crank but it will require a few tricks. You will need to increase you dwell times in the cranking areas of the map to very large values up to 20ms This is to allow for rapid changes of rpm at cranking / start up. If at all an option I would try to go to more teeth such as 24 missing 1 If you follow the help file information on wiring a 4 terminal stepper motor this will suit that bosch part.

Yep we can still do this. Cost wise you will need to flick us an email to either [email protected] or [email protected] Im assuming you are NZ based?

Are you looking for a power supply size to feed all coils? If so I would go to 2mm min for four coils.

The reason you are seeing 12V on both sides is due to the ECU only providing a ground when controlling the solenoid. If you set your AUX to test on this will energise the solenoid and you will see a ground on the ECU side of the solenoid.

The ECU would need a sub-board swap to suit the V8 dizzy. I would suggest considering a newer ECU as things have moved a long way from the V4.

With sensor plugged in so it is powered. You measure the voltage between sensor ground and the signal wire. If this is at 5V with sensor plugged in the ECU will be seeing 5Vs and show a fault. With sensor unplugged you should have no voltage between ground and signal wire. If this is the case the sensor is faulty or wiring of the sensor is incorrect.

Currently only option is switched fuel tables.

Flex fuel is one area that we are aware is not at its optimum currently. Will add this to the list of suggestions.

Could be a vast number of things to cause this. Check for air leaks, correct mixture, correct ignition timing, correct cam timing A must on wasted spark applications is resistive plugs. Are you running cams with a big overlap?

4MB internal logging memory on Storm and Xtreme, 512k internal logging memory on the Atom.

Hi Dennis If you can post your map/PCL file we can take a look at the closed loop lambda settings.There was an issue if you were using a fuel pressure input. This was resolved and an up date to 4.9.8 would cure this. You can switch your 4D map based on an AUX but I'm not sure what you are aiming to achieve by doing this.

This option was removed as it failed to work very well and was not often used. Only option is to use older firmware.

You will be better to scale the sensor in kpa as the rest of the software is geared to be in metric readings. Most sensor are linear in there output so you shouldn't need a cal table. Just use a point A point B cal.
