i'm putting an ls on mah crown vic - and if I give it enough room for the truck oil pan - and I can also use the shallower one.

Went with the truck oil pan to have the option to run both

If anyone has a broken or damaged shallow oil pan around - I would like to buy it.

I need it as a mock up.

Thank you so much,

When I joined v8rx7 lol - I was still in the U.S. Army.

Since then I got a degree in Industrial and Systems Engineering - but I work as a software developer now.

Parts WTB / RX7 Intercooler

Anyone has an intercooler for fc/fd laying around that looks similar to this - backdoor - and similar in dimensions.

See link here: https://www.b1speed.com/3264_Universal_Turbo_V-Mount_Intercooler_21.5x10x3.25_For_FD3S_RX7.html?gclid=Cj0KCQjwiqWHBhD2ARIsAPCDzanSoEsrTZk0gKdRiuBhI75DmJg-bs9m0JoQwLWBumNJp8_Hs8Aum9waAhjMEALw_wcB

Please let me know.

It is sitting in a self storage in Radford - until one day I get a house.

I forgot abut the proper thread. Admin please delete.

It would help me tremendously if someone can run a report for me on this Abarth.

Thank you,

Just a simple feed forward - I wrote my own library which is on bitbucket - and I wrote a blog online about it - but I am not posting it here because ya gonna think I am nerd.

That being said I'm not 100% certain what your goal is.

Exploring and experimenting - that's what I do. If you post a small sample data - it would be cool. I would like to formalize the structure first.

What you are saying its true - that this is only going to apply to your engine but I am not trying to train a nn for general purpose.

The way I see it is you drive the car for a year in various conditions collecting data from your car - while continuously trainning your personal nn at home. When it is trained properly it substitutes the computer - and by the way it continuous to train daily or biweekly... so it learns how the car gets old - whether you moved to a different town -  and stuff like that.

I haven't educated myself yet on fuel management - but at this point I don't really need to know. The reason why I posted this thread is because I was hoping you guys would tell me something in the following lines:

"Here is a bunch of data from  my data logger.... This and this and this are inputs that may have something to do with the *output (whatever it may be such as afr, lambda whatever). This is the recorded output for each row of inputs and this is what it should be ideally."

That's all there is to it.

I went on google the other day and found a lot of academic papers that talk about using nn's for fuel management, coolant management, and all kinds of other stuff. I am gonna have to collect the data myself.

I might be misunderstanding what you are saying but the air to fuel ratios depend on the type of fuel you use.

What i would like to know is what scuter83 was saying above... How do I know how rich or how lean I should theoretically run  depending on engine load, temps, etc? This is the interesting part. Is it done by trial and error or is there a formula for it. Therefore I would create a data table like so:

           |  input 1           | input 2    | input 3   | input n         | recorded output    | ideal output   
          | (temperature)  | (knock)   | (power)  | (something) | (recorded afr)       | (ideal afr)     
--------------------------------------------------------------------------------------------------------------
row 1  | x_1                 | x_2         | x_3        | x_n               | y_r                      | y_i               
--------------------------------------------------------------------------------------------------------------
row 2  | x_1                 | x_2         | x_3        | x_n               | y_r                      | y_i               
--------------------------------------------------------------------------------------------------------------
row m | x_1                 | x_2         | x_3        | x_n               | y_r                      | y_i                               

Air to fuel ratios according to the interweb:

Fuel               By mass       By volume        Percent fuel by mass
Gasoline        14.7 : 1        —                     6.8%
Natural gas    17.2 : 1        9.7  : 1             5.8%
Propane (LP)  15.5 : 1        23.9 : 1            6.45%
Ethanol          9 : 1             —                    11.1%
Methanol        6.4 : 1          —                    15.6%
Hydrogen       34 : 1           2.39 : 1            2.9%
Diesel            14.6 : 1        —                     6.8%

Reasons for running rich are cold start poor combustion, propensity to knock under higher loads, power, car temps. Highly doubt you can train a NN to do your fueling.

Most likely or someone would have done it already.

Thank you - that makes sense that you always want stoichometry; although in the fuel maps i see online its not always that.

So for motivation Ill paypal the first guy $25 for a sorted dataset with the inputs and outputs mentioned in the post.  :bacon: :bacon: :bacon:

I just want to run an experiment with neural networks.
