correct instructions

[hotlinejake]

i have a ms2 v3 board v2.6.14. the hei sparks until i plug in the ecu. i do not know which way to "assemble" the board, or which way is best to control timing. this is a stock tbi chev 350 and it runs with stock ecu. Has small cap hei. Pls advise, Jake Ps i have no datalogs yet

Have you read the manual from the "Manuals" link above?

i am now. Thank you. i still have something wrong, it works perfect on the stim. i am about to check the settings.

[hotlinejake]

I am trying to view/test ign input but my high speed datalogger tab is grayed out. i have upgraded tuner studio and megalog viewer to no avail.

[jsmcortina]

Make sure you are running MS2/Extra firmware.

The "B&G" firmware doesn't support the high speed loggers.

I can now view the ign signal .However it dropped inj1 led on stim. But alas i have run out of weekend.Thanks for your help

[hotlinejake]

I can not figure out why inj1 is not blinking on stim. the fuel calc summary shows two pulse width gauges on, and three and four not on. i had both channels indicated before firmware update. I have tried simultaneous and alternating with no lite on inj1.Could 8pin hei mod affect inj 1 stim led?

[Matt Cramer]

The only effect ignition mods could have on injector output unless you've REALLY torched the board would be preventing an RPM signal - the ECU won't fire the injectors after the priming pulse unless it has RPM.

We have a point test for the injector drivers here if you are concerned they are damaged.

I have tested inj 1 and 2 circuits they are both fine. I re installed daughter board and inj1 still does not blink. I have rpm sig. is there any info i can give u to help me figure this out. It worked before. and it tests good....

Attach the MSQ tune file you are using and someone will check the configuration.

[hotlinejake]

Here is my msq. i hope.

[slow_hemi6]

Just check but I think you have loaded microsquirt code onto your ms2. That's what it looks like given your programmable output options being Aled, Wled etc.

[slow_hemi6]

How did you go hotlinejake?

[jsmcortina]

Just check but I think you have loaded microsquirt code onto your ms2. That's what it looks like given your programmable output options being Aled, Wled etc.

Yes, that MSQ is from Microsquirt firmware. That is incorrect for an Megasquirt-2 (MS2). That needs the Megasquirt-2 version selected when loading firmware.

everything now seems good. Next ? my pulse width is to high, like 19msec at 750 rpm as soon as i turn up the rpms it goes red. its a stock tbi 350 with its stock 55lb hr injectors.is this much open time ok for these injectors and i just need to adjust the guage? Thanks for all the help, I do wrenches and carburetors the computers new. jets and springs are easy!

[slow_hemi6]

Is that on the stim or on the car? Probably be best if you could do a datalog and post that up. There is a guide in the "forum help page" link up in the forums header, at the top of the page. If you are just on the stim it is easy to have a pot like IAT or CLT or MAP way off running condition which messes up the PW as every sensor plays a part in that final PW.

[hotlinejake]

it is still on the stim. I am waiting for a new laptop batt so i dont need an extension cord to hookup the laptop in the truck. zero map... I think im ready to plug it in..

[hotlinejake]

the ignition works, it lit up on residual fuel but didnt keep goin. its to dark not to mention cold tonight.. I will work on it tomorrow. thanks for all the help again!

[hotlinejake]

It was running.. i thought i made a data log but i did something wrong it said no data stored. i did get a log of it cranking now that it wont start. i see two now. will attach both oops one is to big im not positive of what i attached sorry

[hotlinejake]

it started again. here is running log i hope
