your first DW map is at address= D1A3C, 8x16

If you need i will upload map pack to find maps easy.

here you can see two of seven dw maps,
also you can use map packs, but then you will never learn finding map skills

Look for some maps in 2D view (winols).

Thanks for the Screenshots, I'd seen these before, but the rpm on y axis seemed too high and I haven't seen any maps that didn't have the eprom data directly before them (map editing is very new to me)

Here is map pack.

here is what you need ok hit thnx and reputation pass in PM!

Thanks for the above files.

I've got a question..
I'm looking to reverse engineer my Air Fuel Ratio and Maf mg/s to output the Fuel Injection quantity.

So you can calculate AFR by the following formula -
Maf (Mg/s) / Fuel Injection quantity (mg) / AFR (your chosen fuel is most efficient at) * 10

I'll give an example.
(500(a)/28.78(b))/14.7(c)*10 = 11.8(d)
Which in my case is the value I want to reverse engineer.
I want to work out what the value of B is, if I know the values of a, c and d. Something that also might come into play is the rpm... 1750(e)

It there anyway that I can get calculate the fuel from the AFR / MAF in the same manor?
(this is probably quite an easy question, but it's late and my brain isn't working)

Thanks

Formula you wrote isn't good method to calculate injection.

Must presume and test which AFR value will be the best for engine. Factory adjusted maps are usually the best,
you could compare, but it depends what you want from engine, in which altitude is engine running mostly and other factors.
Try about 16,6 - 17,1 at higher maf,rpm valus.
Then calculate lambda from adjusted afr and at last iq_limit_with maf or map.
Simply first calculate lambda from adjusted afr and then iq with formula.

lambda= AFR/14,5 or 14,7?
lambda=(maf/iq)/14,5
AFR= maf/iq
iq= maf/(14,5*lambda)

I can send you excel table which I made, IF YOU CLICK REPUTATION!

Thank you mate! I spent far too long trying to work out what IQ was equal to. I've added them into my excel spreadsheet, so i'm going to have a crack at it later.
