Starting small and simple
- Is there a thread or screenshot for the tunerpro setup for wideband O2.

There is, have you downloaded the Enhanced tuning PDF that has all the relevant info for using the Enhanced tunes?

Do you have one of these?

If you do then you have everything you need to datalog.

I don't think a theoretical number based on displacement is relevant as there are so many variables that can alter the number. Ideally you need to run a datalog and then you can see exactly where in the map/tables the engine runs and adjust from there.[/quote]

Base rate injector comes standard at 361ms/gram the Kinjflow calc with the 777 injectors saying 26.35lb/hr say it should be 305msec/gram --( should I change this as 361 was probably set for a reason)

If you are running stock injectors leave the calculation as is, there are a few different number listed on the web for 777 injectors and the data in the tune is correct.

Thomas2004Rodeo wrote:- End of injector target set to 408deg is that normal also? I have seen the cam profiles in the commodore books talk about 300ish deg but again unsure and rabbit holes scare me now.

The stroke engine cycle requires 2 full rotations to complete one cycle so you really need to think of it as a 720° cycle (360° + 360°) so the 408° is correct but other then that I can't explain it much better, The1 who wrote the enhanced software can give more details, there is also more info in the PDF file.

My pea-brain assumes that the fuel map lets say on a hard static launch would go like in the image
WOT - High load therefore high MGC at say 1000RPM
Higher RPM less load as momentum is built
11seconds later bam let off 100kph or 660ft. (both splits recorded on my app)

Although the thinking is (kind of) correct, the MAF based tunes work a little bit different to MAP tunes and once you go to WOT the PCM goes into PE (power enrichment) mode and does not actually run to the Open loop target AFR map, it works purely off airflow (MAF) and target AFR derived from the PE tables. I'll go more into this in a separate post.

Just leave this map as per standard, the engine will run in Open loop mode during cold start until it reaches the minimum closed loop operating temperature and running time and the O2 sensors provide the correct signal .

What transmission do you run? diff ratio?

What about cooling and thermofans?

Any intake modifications?

Plot twist - with the conversion I never hooked up an OBD port due to never having needed it in the past (I have the haynes manual and can use a parts or donor car to make that work)
Then I assume laptop and happy days ->> side quest.....My memcal is EPROM light cancer box erased Will that be an issue? not being NVRAM

It is not a problem as such but it makes burning new tunes very long winded. NVRAM is easiest but another much cheaper option is getting a EEPROM memcal which lets you erase and burn a new tune without the need of a cancer light.

see viewtopic.php?f=14&t=3650 (hopefully The1 still has some stock).

4L60E and standard rodeo read diff 4.55 from google (RA 2004 Rodeo Petrol originally)

Does the transmission shift at the appropriate times or are you shifting it manually?

That is normal until recipient reads it, then it goes to your Sent box.
