I am re-collecting all maps. If you have a map please put your complete combination down, and how you calibrated the MAP sensor. It seems all the base maps I put out get epic fail, and all my customers have the good ones. So I'm attempting to correct that. Thanks!

Index of /adaptronic/maps
sort by date... later is better.

2001 Miata
COPs (waste spark)
550cc injectors (low impedance, sequential)
ECU shares CLT, CKP, CMP, VSS, TPS, Neutral SW, Clutch SW, KS
Adaptronic controls ONLY: Inj 1-4, Ign 1/4 & 2/3
Adaptronic outputs a phony MAF signal via a circuit that converts PWM to voltage.
(this is done using Fuel Map 2 as a 3D output)
All other Mazda ECU functions are passed thru the jumper harness.

aw heck just look at my setup spreadsheet:

after look at your ftp and xls i realized your not human.

Okay,

2002 NB, 600cc Injectors, 3 BAR MAP, AEM UEGO, OEM O2 sensors, Open Element IAT sensor, BEGi GT2554 turbo...

Car idles okay, had a miss when hitting higher boost levels but think it is related to an injector problem. Car is down while wating on the repairs. :(

Comments and feedback always helpful! Also curious about how everyone is calibrating their MAP sensor... I read 113kpa at ignition on and no engine running...

Cheers,
Prospero

Prospero, feedback on that map:

1. Find out your injector dead time and set it NOW... it's definitely wrong and is the basis for all fuel map tuning.

2. It'd be a good idea to figure out the max boost your running now and set your overboost protection a couple psi over that. (7 kPa is about 1psi) set the 1 sec a little higher.

3. Your throttle overrun is not doing anything until you set the min water temp to somethign more reasonable (60C is good).

otherwise it looks ok. nothing that will keep you from running normally I dont think.

Yikes those injector dead times were imported in the base maps some how... I'll fix that...

Prospero

Y8S,
Thanks a million for looking at this for me! I will resolve all the goodies ASAP... still waiting on my injectors to come back from the repairs; but will look up the dead times for the 600cc injectors right now!

Man, there are just soo many options!

Cheers,
Prospero

Travis,

You have the dead times for the 600cc injectors, right I have mine at
deatsch at this very moment and think that maybe I can test the car Monday night

If you would not mind sharing this info... I will put my fingers to work.

Thanks and best reagrds,

It needs to be inverse exponential fitted, but the software for that is on my other computer which is being borrowed. This should work pretty well.

TravisR,
I’m pleased to share my map, the fuel map was tuned professionally on a dyno the rest is my own work, the car is driven by my wife so it has to be user friendly. Starts easily and idles smooth. I setup my MAP sensor (2 Bar) with one of these, Mityvac very easy to use and you can use it to bleed the brakes.
The engine: 1.8l , ceramic coated after market headers, 2.5” exhast,and high flow cat.
M45 supercharger 7psi, TD type intercooler, 2 throtle bodies, 360cc injectors, aftermarket fuel regulator 42psi.
Adaptronic e420c ECU

OMG, it was too early this morning when I read this post! Inverse Exponential Fitted? WTF does that mean... I have had 2 cups of coffee and it has not become any clearer yet. Please, teach me master Danielsan needs to learn wax on and wax off! Hell, I don't even know what window these settings go into!

Argh, I need to spend less time at work and more time playing with my car!

Cheers,
Prospero

who says "inverse exponential"? you mean logarithmic? negative exponential?

TravisR

iTrader: (9)

One of my degrees is in math. All that stuff just blends together. If we look at the y-axis on an exponential graph with respect to x the y values go nuts, but they start at 1. On this graph the values go the opposite way as x=0 y~infinity, and as x=infinity y=~1. So inverse exponential

I actually ended up going with a 3rd degree poly fit for the steep side, and maybe a 5th degree for the flatter. The exponential just wasn't cutting it.

Sorry if I missed it from a previous post. What is everyone using for the IAC frequency?

Prospero

I heard that 500 was the best number since the factory setting is like 450 something

TravisR

iTrader: (9)

Anything above 200 that doesn't make noise is ok. The computer cycles at 200, so its not going to make much difference if its at a higher value then 200 besides getting rid of the noise.

Prospero

Ahh, makes sense!

Ohh, quick question... where do I enter the injector dead time correction? I am slowly looking in WARI but have not seen it yet.

Thanks,
Matt

Prospero

Oh hell, never mind! Just found it... it's sorta hidden in the middle of the screen; but there none the less!

But what is the purpose of secondary corrections here?

Thanks,

OK thanks. I'll try 200 Hz. It is set at 100 Hz right now.

BTW I used Y8S settings for fuel enrichment. Works good. No throttle stall even when the engine is cold.

How about putting this into inputtable values? Propsero's dead time was wrong because mine was wrong but we were running with what was supplied. Might be the issue that I have with the lean tip in but I don't know how to covert the supplied values to data that I need.
