it won't fire up!

[skylinedriver59]

Hey guys

I finally got around to getting megasquirt. I went with megasquirt 2 w/PCB3.0. I got everything wired up and ready to go based on the write ups i found. I mainly went of the DIYautotune.com write up. however most of the info i got is always for MS1 and MSnS. I know a lot of people are using MS2 now cause i read a lot of post. So i wanted to know which write ups or post did you find useful for installing megasquirt 2?

this is where im stuck right now. I had trouble getting my laptop communicating with megasquirt but i took care of that now im getting a few errors and warning messages. one of them says "controller code version does not match signature in megasquirt II.ini. but I cannot find the correct .ini. for MS2-Extra 3.1.1 firmware does anyone know where I can get it at?

Thanks

Manny

matt from diyautotune is a member here (who knows maybe he'll chime in), as for the writeups, most of them have to do with the wiring, and most fo that is unchanged (remember megasquirt 2 is a daughtercard in a megasquirt 1)

I'm not familiar with your firmware but you have to create your own ini file and burn it to the controller, which is a lot easier now than it was when I did my first, you had to jumper some pins and use a old dial up program, it was a pita, much easier now

Thanks for the reply evildky.

I touched bases with matt and he solved my error problem. I was using Megatune when I need to be using tunerstudio I guess megatune reached its end and its not compatible with the new firmware codes. SO thanks to matt I'm ready to tune with tunerstudio.

thanks for clearing up the write up issue. hopefully all my wiring is right since I used Matts write up on his website.

Another question I have is tunings? can I follow the same settings that are on the write ups for MS1?
How do I know which setting to put for my car? for example engine constants settings, injector setting and characteristics and ignition settings.
I know I have to set the spark to (going high inverted)

[evildky]

megatune had an internal write up on how to set and tune your fuel and ignition tables, I'm sure there are others, I personally just started with someone elses maps and tweaked form there with the aid of a wideband, to really tune the spark tables you need a chassis dyno

also when you set everything up it comes up with an estimated ve to begin with and you can scale the tables from there with 1 click that'll get it running enough to tune, or simply copy someone elses ve tables and tune from there

as for the settings thats gonna vary depending on your setup and your firmware version, I'm running HEI modules so mine is different right there, and each firmware version has it's minor differences for how the info is added and how many options you have, just take your time and realy wrap your head around it, I think I have to reread for a weak before I can fully get my head where it beeds to be for any serious megasquirt projects

the injectors well thats pretty self explanitory, just a matter of if you are running high impeadance ro lwo impeadance and wether or not you are runnign external dripping resistors, otherwise it's just a function of calculating your "req fuel"

[skylinedriver59]

When using someone else map can I load the MSQ or Do I just have to copy Their tables?

[evildky]

you'll have to copy theri tables unless you are running the same firmware

[skylinedriver59]

OK I had some stuff come up and I had to lay off the Z but I had some time and worked on it. I was trying to set timing according to write-up by 'mobythevan' at Hybridz.org. He says to set number 1 cylinder to TDC then turn it back about 50 degrees BTDC which I've done. Then he says to "Loosen the distributor and give it a turn by hand with the MSnS powered up. Turn the distributor until you see the middle LED come on. When this lights up stop and tighten the distributor back down."
I'm a bit confuse by this does he mean to loosen or remove the screw that holds the diz? And do I have to turn it clock wise or counter clock wise? and do I have to do full turns or just back and fort?

I turned my diz by hand and at some point my fuel pump kicked on real quick and my coil sparked it did it a few times while I was turning the diz. but no LED stayed lid on my MS.

The Good news is that I fired up the car and it ran it was smoking but It fired up which I would think that would be a good sign! Right? I just have to work on my tunning and timing.

[evildky]

moby's write up is based on ms1, and fyi the distributo spins counterclockwise and the idea is to advancethe ignition which means turning it clockwise but ultimately you can adjust the timing in the ecu, if you have it running your almost there you just have to get the tming light and the ecu to reflect the same timing

[skylinedriver59]

So how is this done? DO i pull out the distributor and turn the shaft clockwise with the cap still on? or the way I was trying to do it was I removed the cap and remove the distributor bolts and turned the distributor housing clock wise while the rotor stayed still cause its still attached to the shaft.

[evildky]

if you have the car running you can adjust as needed with the software, again I haven't used your version but it's in the timing settings, you need to adjust the control settings untill they match up with timing light readings

[skylinedriver59]

Thanks evildky! you make being part of this community wurth it.

THe Car is Running and it stays On and Idles. I want to see If anyone has a MSQ I can use as a starting point.
Im running MS-II PCBv3
My set up is Stock L28et with P90 head and N42 manifold
-T3/T4 hybrid turbo
-MSD 2225 electric fuel pump
-upgraded fuel rail
-240sx TB
-Arizona Z TB spacer
-CX racing FMIC
-3 inch exhaust
-Stock distributor with Z31 module
-injectors are 450cc at 38psi, 480cc at 43.5psi (3bar)or 500cc at 47psi

I have some files from the map sharing post but dont know which one I can use
any help would be appreciated, Its about time to get my Z running and driving.
Thanks guys!

[evildky]

have you got the idle timing to match up yet? thats the first step, you can copy moby's ve's as a starting point

[skylinedriver59]

Yes timing matches

[evildky]

sweet, so how's it running? you using someones ve's or did you scale your own? ignition maps? there is a whole theory to both but if you cans tart with someone elses it gets you moving a lot quicker

you have a wideband?

[skylinedriver59]

It runs! lol it has no acceleration.

I have a LC-1 wideband on order. Im going to use the VE analyser live (whatever its called). but dont know what to do about my ignition table?

[evildky]

how do your VE tables look? acceleration wizard?

ignitin cna only truely be tuned on a dyno, you hold each bin and tweak timing for max hp, if oyu experience knock you back it off a couple of degrees, I actually started wiht moby's maps and made only minor tweaks

[skylinedriver59]

I finally got my wideband in so I can start tuning but I have a question does the wideband have to be connected thru the serial port on my laptop or just as long as the wsideband analog out put 1or 2 is connected to the megasquirt o2 input?

[evildky]

you just need the wideband hooked to megasquirt, and be sure to change your settings in megasquirt to work wiht the wideband oyu got
