No worries, all sorted last night.

BTW you have to change the Vidigauge dial from AFr to any other reading and then back again and it will show the wideband AFR reading.

Hi,
I did understand what Rob said and therefore asked what block to influence.

We used the racelogic quite a while in racing and did not have any engine issues. What would be the failure mode with a turbocharged engine?

Anyhow I  thought about implementing the racelogic idea into the E1280s but still struggle with their idea of stopping injection to each 2nd or 3rd or even 6th cycle in a 4 cylinder engine. See their manual page 43. This idea gave us a finetuned power loss to the engine than just in around 25% steps with a four cylinder. I cannot find a "counter" in the E1280s control blocks distributing the injection outage to - for example- every 6th injection...may I need to think about that longer 

In WARI on the Special Functions tab you can select the LC-1 in the Seond Serial Port box but in the Analogue Cals/Tuning Mode tab in the OX Sensor box there is no LC-1 to pick from.

What should I set this setting to?

The "Oxygen Sensor" data in the "Analogue Cals/Tuning Mode" tab refers to Pin A6, labelled as EGO on the wiring diagrams.

If you don't have anything connected, you can set it to none.

The manual also says the following which is worth noting

If a serial-connected wideband oxygen sensor is selected and connected, the
AFR from it overrides the AFR calculated from the analogue input. However
if there is no data from the serial device for a given period of time, the value
calculated from the analogue input is used instead.

Fitted an Innovative LC-1 wide band O2 sensor on the weekend but I have a couple of questions.
The LC-1 is connected directly to the second serial port on the E420C with the original narrow band sensor disconnected and removed.

In WARI on the Special Functions tab you can select the LC-1 in the Seond Serial Port box but in the Analogue Cals/Tuning Mode tab in the OX Sensor box there is no LC-1 to pick from.

What should I set this setting to?

Also It shows an AFR reading in the F2 window but no reading at all on my Vidigauge. Any ideas?

Hi Andy,

Just so you know, when it says 'Reset ECU' in the firmware flashing utility, that is a request, not a statement.
We're going to change it so it says PLEASE reset ECU.

Cheers

We just ended the 9,5Ton truck pulling competition 2010 and came out 4 place overall.
I think we done very well al do we had some ups and down with the turbochargers blowing up coming short on points to become 3 place in the competition.

Electronic activated diesel injection makes it possible to get a massive amount of power out of a modern diesel engine.
This year we run an almost standard 16Liter engine to gain information and experience so we could step up to bigger injectors for next year meaning more power.

The e1280c ECU made it possible to run this engine to the max and due to all the data logging we did we were able to make fast changes during the year.
We also like to thank Andy’s team for supporting us in the development of all our projects.

As Rob was telling on the 1280ECU you can do what ever you want with cutting fuel as an example but you have to understand how to write a program that will make it possible.
@ this moment the standard config has a hard cut that cuts all cylinders and a soft one that will cut half of the cylinders.
The best to start off will be in the injector trim menu if you want to cut fuel but you have to change the program in order to let it work.

From experience retarding and cutting half the cylinders will work in most cases.
We run a 1600Hp diesel engine and controlling this engine within 100Rpm maintaining full boost and there for full power if needed by first retarding injection and if this dos not work cutting half cylinders.
For a petrol engine we always use ignition retard and cutting ignition as a fuel cut can lead to engine damage.
Also reducing dwell time will work very well al do on some smart igniters this may not work as the igniters controls the dwell time it self.

Don't worry peeps - Scoff to the rescue, I have V7 on board and Wari 5 on my laptop.

Hi there,

Sorry to post this in this section, but I am not able to create a new topic within the firmware section.

My ECU e420c (I think this is e420c, may be e420b how can I check?) still has firmware v1 on it, and I was asked to make sure that v7 was installed before it was mapped, I have downloaded v7 and loaded it into the flash downloader through wari and when I try to flash the ECU it says '  Failed to read 4000 (11 times in a row)
Too many failures.' and has 'reset the ecu' in the top of the window.

I have disconnected my battery to try to reset the ECU but I still have the same problem. The question is. How do I reset my ECU?

Regarding the TPS only map...

- slightly increase the fuel amount from 3000 to max rev (or decrease below, it is rich enough)
I'll have a play with that; and I always try to make untuned parts of the map a bit rich.

- change to a "Max RPM step size" of 250 (2nd tab -  gives you more accuracy)
Can do, as I am rev limiting at 7600 presently.

- TPS-based Enrichment is set to 0, meaning no enrichment at all (if I understand that option correctly)
Set to zero as recommended when using asynch throttle pump.

- Asnch. Accel. Pump Gain is 10%, meaning you don't get any extra squirt when TPS change is below
10% (e.g. form 0 to 9%) which could explain lean acceleration mixtures - should be changed to a lower
value
That's a gain control, and lower numbers mean greater sensitivity (the 10% is meaningless).
I have experimented with other values, but the 10% setting seems to work OK for now.

- 12.5 is a bit rich to my mind, 12.7 should do
Those figures were a bit rich for safety reasons... I will back them up.

- set to run "open loop" above 80% TPS at the moment. Why not set to 100%?
Came out of the box set like that... thought it was standard. But I have found the control
and will change it to 100% TPS.

- remove "update other parts of the map" option (had bad experience with it)
I thought this box had to be ticked to get the Rapid Learning to update cells ??
EDIT: Found this... "The selection “update other parts of map” is used for tuning, it will give a base
point equal to the current value, for all untuned points of the same load as the one being tuned".
So yeah, I'll uncheck that box

As far as the MAP x TPS tune is concerned, I shall let that alone for a while.
