Any of the wire-ins would do the trick nicely. If on a budget the Atom could be used but does have limited IO. The Storm is the most likely pick for the application. Plenty of inputs and outputs to control all functions. Extreme could also be used but would likely be over kill.

Thanks for that. Couple of things noticed. Duty cycle is very low some solenoids will start to open again at values under 30% Suggest raising all values to 50% in the base duty cycle. Frequency should be raised to 200-300 hz. Suggest using a virtual aux as assumed you didn't have the need to switch the clutch in and out. So no actual output would be required. Is this a Bosch solenoid?

To calculate the current take the injector resistance add it to your ballast value. Divide the answer in to the battery voltage. So with a 12V supply a 2.2 ohm injector and a 4.7ohm ballast calc would be 12/(2.2+4.7) which equals roughly 1.7 amps Chances are you could drive them harder. Depending on what resistors are available. Also injector dead times will play a big part at small duty cycles. Ideal would be to get the injectors tested.

Send in the ECU for repair.

The 4.7 ohm resistor box would help assuming it is a current problem. They would need to be 25watt resistors minimum. The Vipec Injector driver would also work.

Hi can you post your map on here and we can have a look at the settings. The AC idle up is based of the aux output you could use a virtual aux if you dont have to switch the AC clutch.

You need to check that pin 16 is not stuck at ground all the time. You should see 12V when key is off and this should then switch to 0V when key is turned on.

The attached image is how it should be wired.

Woops I should never assume! The ECCS relay is controlled by a transistor on the board. When 12V is applied to pin 45 it should supply a ground on pin 16. If this fails when 12V is not present on pin 45 you will still have a ground on pin 16.

If you have to make the pulley and are going to have a cam sensor then 24 evenly space teeth might be easier to make. Either way you will be fine.

Sounds like you could have a busted ECU. We can still service these if you get it back to us.

This was an over site back in the day. The cam stays active right through. No means to turn it off. G4's of course have this well sorted.

Thanks for helping with this one guys.

If you select evo 1-6 trigger pattern it will set it correctly. The trig two is on falling edge and trig one actually uses both for better resolution.

Can you post your PCL file. Ill give it a run on the bench to see if I can replicate the symptoms.

A large number of technical inquiries are received regarding problems due to incorrect wiring of auxiliary outputs. Incorrect wiring of solenoids and relays to auxiliary outputs can result in the following symptoms: · ECU not powering down when the key is turned off. · Accessories such as engine fans coming on when the key is turned off. · Repeated clicking of relays when the key is turned off (machine gun sound!). · ECU draining the battery over a few days. The root cause of these problems is the wiring of hot fed (direct from the battery positive terminal) or ACC fed (key in accessory position) solenoids or relays to ECU auxiliary outputs. Each auxiliary output basically consists of a low side driver and flywheeling diode. A low side driver is a power transistor that can switch a load to ground. Flywheeling diodes are required for the driving of fast switching devices such as ISC solenoids and VVT solenoids. Flywheeling diodes are also essential for reducing radio interference noise. Unfortunately, the placement of flywheeling diodes means that if power is applied to auxiliary outputs through a solenoid or relay when the ECU is powered down current will flow through the flywheeling diode causing the ECU to power back up. As solenoids have some resistance, the current that flows back into the ECU (back feeds) is not usually enough to power the ECU up properly resulting in the ECU powering up and down continuously. This causes unusual behavior by the offending solenoid and possibly other solenoids as its current is switched on and off. This is taken from the help file. A search on back feeding will give more info.

As to the question on if a solenoid can be used it depends on the ECU. Plugins designed for a stepper can not control a solenoid. However all wire in ECUs can.

You need to slow the motor down. By putting load on to it with the throttle closed. You can load it up on the clutch. You might be able to take the stepper out and wind it closed. Also check your idle hot and cold numbers. It could be worth lowering these.

It is likely if the idle is this high the ECU has locked idle control out. If you can load the engine up and get the RPM under 1500 there is a chance the idle will then come right. This is assuming that the TPS is reading correct at closed throttle. Failing that it could well be a damaged ECU.

If you have a look at the latest G4 PClink you will find in the help a number of pinouts. These will apply to the G1 you have for all the critical bits. I can assure you that the ecu is a 44s/V7 ecu for the software codes you gave. And the fact no other G1 ECu uses 3 micros.

On the g1 a retune would be required as the row steps change when switching map sensors. A G4 would allow the swap with no need for a retune.

I need to check the Firmware and VTS version you are running. If you could upload your map would also be good.

Multi tooth using the 4 even spaced teeth will be the go assuming you still have a cam sync with a single tooth.

Suggest frequency be set to 6khz Do a full power run and log knock levels. (Be sure the engine is not actually knocking) Set threshold tables to about 25% higher. Would also suggest some logging at light loads to allow setting of thresholds at lower power as well. Also you can not share the sensor with another device. Each device will require its own sensor.

It is a G1 LEM running V5 firmware. When first sold would have been set up for a 1UZFE engine. Given its come off a Honda it has been reconfigured at some point in its life. It will be able to run individual throttle bodies but a G4 would do it much better.
