Thread: Base maps - A good place to start.

What would you like instead?

No man I'm saying if you don't have enough time to send it now I'll wait till you come back

What if I just e-mail you the file with the entire tune on it? I assume that would be good for you? I can send you a gasoline or an E85 tune... The E85 tune is a little smoother than the gasoline tune but both are good. I know I have the E85 tune for sure on my desktop.

Either way, the timing maps are basically the same between them. The E85 might be more agressive by 2 degrees or so in boost.

And unless you have 720cc injectors and a GT3076R the fuel delivery part of the tune is going to be mostly useless.

i would love a copy of your timing map as well for an sr20det.

Oh the pics are back up... Sweet!

kinda new to the tuning thing. A map from tuner pro or NDS or AEM will all show the same information right? Just sometimes in different units?? I've played with rom editor a little and it confuses the **** out of me. About all I learned how to do was change mafs, and k values a lil'.

Almost always the timing maps will all be the same (degrees of crank rotation versus engine speed). Fuel maps can vary wildly depending on what fueling theory/algorithm and air measuring device(s) are used.

First pick one of the possible air measuring device(s):

• Manifold Absolute Pressure (MAP) sensor + Intake Air Temp (IAT) sensor
• Mass Air Flow (MAF) sensor
• Air Flow Meter (AFM) sensor (AKA barn door)
  

Next pick one of the possible fueling theories:

• Speed Density (RPM + throttle position + pressure + air temp)
• Pressure-based (pressure + air temp)
• Air-Flow based (MAF or AFM)
  

And finally pick one of the common fueling algorithms:

• Volumetric Efficiency (VE) based
• Raw injector pulse width based
  

Fueling maps will be different for every combination of the above choices.

ok makes sense. I'm running a calum basic and i was just curious if the .bins for other ems' could be used. I need to change my fp from 4bar to 3bar because of a bad fpr and i'm having trouble finding the bin i need

Vadim and I have had a talk about this thread, and this idea. We still think it's a good idea and worth pursuing but have decided to change the format a bit and I want Vadim to take over control of it so he's made a new thread that is making this one obsolete.

Here it is: http://www.sr20-forum.com/tuning/22279-timing-maps-tuning.html

Vadim is going to lock this thread so everyone should go to the new one to participate.
