Thread: MAF->MAP conversion with Tunercode?

That's awesome!

The second method would be much easier to use and understand.

With the RTv1 ecu I ran on my s13 ka-t, I wired up a gm 3bar map sensor to my lm-1 and logged pressure through LW2/3 while calumsult streamed consult parameters into lw also. Made tuning easier being able to put a face to TP instead of being just a number. Then I would go into tunerpro to make changes to the bin...

That's 3 programs just to tune my damn setup lol, and sometimes one would malfunction and screw my tuning/logging sessions, usually at the worst time!

Anyways...

Now that the ecu would be reading pressure, would boost control be possible also? Does the ecu use pwm to control boost pressure on oem setups?

May be getting a little ahead here haha.

I owe John a beer. IMO you're missing half of the gains from a MAP sensor if you can't get rid of the mind-numbingly complex TP axis.

Boost control, along with everything else stand-alones have that is technically possible, would be included.

On the S13 SR20DET, boost control is on or off (ie: no PWM), but I don't believe anyone with a swap is using the stock boost control. All it does is limit pressure to the WG during spool-up based on Load, TPS, and CLT.

MAP is much easier on new installs and much cleaner looking. There's a reason why most standalones prefer MAP as well. You may like them but personally the only trouble that I've had out of my car has been with the maf, whether it be stupid stuff like wiring or VQ maps, etc. You just can't do much with them.

Keep up the good work Dave. So this is going to be integrated into tunercode as well as the standalone version you mentioned??

Right now I'm leaning heavily towards the complete re-write version (tune like a stand-alone), rather than releasing 2 different versions of TunerCode SD.

Thanks,
Dave

Didnt have my cookies and milk before bed.

The EVO guys are doing it with good results

Would there be a need for a air inlet temp sensor with a map sensor setup? Factory Map sensored cars i have had have needed a air temp sensor, and the last aftermarket system i had a air temp sensor as well.

My mate and i did some data logging with a map sensor, and to be fair the basic data was very similar from a basic shape point of view to a maf on the same car.

Obviously the Tunercode genius's are a bit ahead of my random minor work, so im looking forward to this next level.

Afaik my '98 Primera P11 originally SR20DE now SR20VE has an AIT sensor danglin around the air intake pipe.

Yes, absolutely. I'm 100% positive Dave knows this, and even mentioned it in an earlier post.

Edit: It was post #9 in fact.
