Megasquirt Maps and Tables

[19cturbo]

are you even able to make boost with that fuel table?

 

yeah, its not done yet

[383chevelle]

Megasquirt MSI 3.0.

stock 86 intake

2x stock 86 850 cc injectors

home made trigger wheel in modified distributor housing

Gm coolant temp, and IAT sensor.

16g

7psi for now

I just realized that I screwed up the required fuel I told it I was using 650 injectors when the 86 has 850 injectors, well here are the tables so far. I am most concerned about the ignition table. I just want to make sure that is is not crazy aggressive. I would like to be a little on the safer side of the ignition for now.

[psu_Crash]

That ignition map is VERY conservative. I hope you are running injector resistors with your PWM current % at 75. Low Z injectors should be more like 25-30% without resistors.

[383chevelle]

Yea I have resistors in line with the injectors. Most of the constants were set by the previous owner. I will have to do some reading to better understand what this does exactly. I am starting to worry that everything the po did was wrong. I actually used yours ignition map and scaled it back a bit. Sad part is the previous owner was running an ignition map that was 7-10 degrees retarded from this map.

[jisleyjr]

Ya your ignition looks too conservative to me. I am running a map similar to post #10 in here. http://www.starquestclub.com/forum/index.php?showtopic=130592entry1279670

 

I see psu_Crash's map is below that and it looks nothing like what you have.

 

Looking at your VE table i have to ask if you are having any issues with running lean when you are doing a light footed acceleration? In the 86 - 40 kPa from 2500 - 5000 rpm area specifically. I noticed in my own tuning recently this was the area that caused me to run lean. But how often do we 'lightly accelerate'? Ha

[383chevelle]

I sort of copied psu-crash's table that he posted in this earlier in this thread, not the one in the linked thread. I knew it was conservative but didn't think it was overly so. If you think that table is conservative you should have the the one the previous owner had loaded in the car. The afrs under light accel are very good actually. I am having a problem with really rich condition on tip in which I caused by wanting to make sure it didn't go lean. I am tuning the accel enrichment slowly. I am hoping to get some time on a friends chassis dyno to so I can fully tune the VE map. It is a eddie current dyno so you can set a speed and work up the entire load scale at one rpm bin, it is so awesome.

[psu_Crash]

Being conservative is safe I wouldn't worry about changing much until you can get on the dyno.

Just for reference here is the map that made the 363/418 dyno pull for me.

Stock 86 tsi.

Ms1 extra v3 (cant remember the code)

12a turbo 14 psi

Trilogy 850cc

2.25 exhaust no cats or muffs

Stock fuel pressure

93 octane fuel

2nd gen mighty max distributor and stock coil

Stock intercooler

this is my daily driver tune for now. the warmup enrichment needs work runs lean till 120 degs.

This a slightly modded psu_crash ignition map. Thanks crash

i decided to give this a shot, aside from being tbi, our setups arnt to far different

i assume there are no changes in your VE for the meth right?

i went to the store earlier, and take off and up to 5 psi is amazing, but it kind of died off after that. though different climates, different setups, etc make a difference

I would have expected better results with your setup. Works like a champ for me. I shoot for 11.8-12.0 AFR with the Meth on at WOT. I would want to be richer without the meth spraying. I keep saying I'm going to set up dual ignition and VE tables to switch when meth is off or encounters an error. It has an output specifically for that purpose. Then I might give it another degree or 2 or timing with the meth on since that timing map pulls timing pretty quick in the first 10psi.

 

Shoot me a datalog and I'd be more that happy to look it over/give suggestions

ill make a pass up the road tomorrow with a recording. though i do still need to hook up my IAT sensor lol

You should do that FIRST! I ran without an IAT hooked up when I first installed MS. It will make a huge difference in your fuel maps. I went to the local yard to grab a sensor. Hooked it up in the parking lot and tried to drive home. No dice, way lean. So I had to unhook it until I could make some serious changes.

was the same thing in my miata lol

If the meth is spraying before the iat, you could just adjust the iat/clt related ignition settings.

Disregard, dynoed megasquirt settings and logs to be posted below. Edited October 2, 2013 by CaliConquestAlex

[CaliConquestAlex]

I will post pictures of my megasquirt settings used for the dyno runs at insane speed tonight as well as a datalog of the runs.

[CaliConquestAlex]

Here are the settings used for my dyno run. Car specs are in my sig. 95lb low impedence inj. Ms2 v3.0 hardware. Ms2 extra 3.2.5 fw. The tune file and log file can be downloaded from:

[taeisallin]

What kind of power did you make? Dyno sheet?

[CaliConquestAlex]

I haven't had a chance to scan the dyno sheet, but it made 288HP and 305TQ at 5100 rpm and 15 PSI boost. It was running pig rich, but it pulled hard all the way to 6k rpm. These settings will definitely be helpful for someone to use as a base tune. I tuned the fuel myself and used some of the other spark maps posted here as a guideline. I used the tunerstudio autotune function to dial in the fuel maps to my AFR table. Edited October 2, 2013 by CaliConquestAlex

[CaliConquestAlex]

Here's an updated datalog after a wastegate spring swap for more boost. Max boost is 20 psi.

[scott87star]

Those are very good numbers, I bet its pulling hard now!

[CaliConquestAlex]

Thanks Scott. It's running very well!
