Well I was tunimg my car all seamed well I did over tune so I wanted dump what I had just did and start from scratch so I closed the feul tuner ans ms prog qwith out saving then re open the file and well I lost all my setting and it says can't burn to ecu voltage to low I know it not but wtf is going on? Anyu help could help thanks

 

I've never seen that happen... You should be able to reflash the firmware and reload your old msq to get you going again.

Ken

 

Hum.. I'll have to dl it tonight and drive up here in morning with new file as long as my dam com ports not the pob

 

Well I walked my wife through getting the fimware. its diffrent then my current but at lwastt il be able to see more activity and if it my prob..

 

ok so my wife got me the newer 2.0 firm ware i flashed it to that one and tps and stuff seams to be working since my board is setup for 1.02 il reflash it in the morning and i should be back on the road TY for your help

 

2.1.x is going to require a rewiring... the second trigger moved to JS10.

Ken

 

And also you'll have to export all your tables then import them into a new MSQ for 2.x. At least, that's the easiest way of doing it.

Sorry I didn't get your message last night. All the ringers on my phones are turned off and I also didn't have my Blackberry on. I only saw that you had called this morning.

 

will do. il just keep the current firm ware for now. that should at least get my car home tonight lol


no prob im just happy to have a data phone now that i can post my prob on the on here while im stuck and get some answers on the road

 

Well reflashed it 3 times, as my third last map I made is making the megasquirt crash each time I load it. Figured I'd post up that map tonight when I get home I'd like to know y its crashing the firmware I might send it to diyautune and see what they say. Car still won't start dice then its close to catching but just won't. Dj55 is coming tonight we shall see what happened

 

There were occasional serial comms issues in 1.0.x, but those were fixed for 2.x.x.

I recommend that everyone using an ms2 should use ms2/extra 2.1.0 or higher (betas). The latest 2.1.1 beta code contains a new staging method that works better than all the previous methods.

ok so i have been with out good sleep for the past 2 months, and well i keep forgetting of missing simple things all the time. and i looked at the leading spark plugs wires and noticed they where infact backwards
so i pulled them off and reconnected them the same way causing the same prob. once DJ55b came over last night we pulled the spark plugs out and unfolded the car, cleaned up the spark plugs and noticed the trialing where not firing. so we installed some other plugs and went for a tune, 1 hour of tuning and the car was pulling harder then the stock ecu was and hitting 5 psi boost much faster. we stop to change some gauge settings and add the proper innovative wideband to the ms program. i shut the car to test our warmup enrichment, start the car up and now its way to lean and runs like *** stumbles all the time... so odd. so we reloaded the map and seams like that glitch wont go away . im starting to think i have some bad ram in my notebook casing files to be written wrong to the ecu and making it crash.. il keep u guys posted but as per our tuning tonight all was well!!!

 

The order of the leading wires doesn't actually matter as the coil fires waste-spark.

Could the glitch simply be that the ECU is entering closed loop at the wrong time (now that you have activated the wideband) and leaning out the mixture? Check your EGO settings.

 

what what should those be set to? i sent an email to diyautotune and have been telling him of whats going on since the day i stop by your shop Aaron, he informed me that if the spark plug wires are to close to an input to the ecu it can triger high enough voltage to clear the ecu... sort of like an mini emp ish..... that's what he had to say about my wtf night.... im going to re install my MS software and get rid of the 2 versions i have in there and clean all that stuff. up then il load the files and see where that gets me, i still cant believe how well the car runs when it dose run.

 

You need to adjust the TPS and MAP trigger points on the EGO screen so that the ECU only tries to correct the mixture at low load. If the TPS value is too high, for example, you could get the ECU trying to correct the mixture even at high throttles.

 

ic... now the tps is set to 1 to 900 or something like that and it sweeps like a dram, now as for the wideband i think i need to connected my computer to the interface and have a look at some settings there as its not showing proper values on the ms, now what do i need to set on my ms to tell the ecu not to correct anything with EGO as i just want to drive a car for now and worry about that extra mode later ?

 

ok so i uninstalled all ms software and reinstalled it all re flashed my ecu, and loaded my "base map" (car starts and runs ok but rich) after doing this i imported our tuning fuel table and the car hits way way to lean and stalls and or runs like ****. so i re import my base map all seams well. so i open notepad up and copy the fuel tables from our Thursday map as something is wrong with the file?? so i copy the table to the working fuel map and still same prob for some reason now the tuning we where doing changed from being perfect to way way to lean... its maxing out my wideband O2 system. il pull the spark plugs out and recheck them.... wait that would make it rich.... hum... ya im confused as to Y the car would run so good for 1 hour of tuning shut the car off and have it run supper lean with no changes at all... all sensor seam to be accurate and reading the same as they have always been. i will try to retune my base map sunday and see if can get it tuned and stay perfect this time around..

 

Sounds like you didn't burn or you didn't save the burnt copy.

Ken

 

whats odd tho is its just a bunch of numbers in a table correct... so if i copy the tables, just the numbers that make the fuel graph and put them in a working map and rebuilt the table it still runs like crap. i see what your saying tho.. like the tuning was never done as it was never burnt to map.... each time we fixed some thing or every other time dj55b would Burt it u could tell when the ecu would stop for that split second or at least i hope its burning. il do some tuning today and and see if it dose it once more.

 

To disable all O2 correction, go into the EGO settings window and set "Controller Authority" to "0%".

The TPS and MAP setpoints on the MSII for EGO are set as a % value. Once you have a properly calibrated TPS you can observe the TPS and MAP values in Megatune and decide an appropriate level for the closed loop trigger points.

But you can't set up EGO correction until the VE table is tuned.

As for the lean, when does it happen? If it is only lean for the first minute after starting, then turn on the afterstart enrichment. Also check the coolant temp correction table. Changing the VE table alters the percents needed for warmup enrichment.

 

ok it was set to that. i think sam found the prob... its my pos BOv.. its leaking vacuum and not the same amount each time. if i shut the car off then start it back up the bov will move or shimmy or some thing allowing more or less vacuum making witch messing up the MS ve tables like crazy cause its seeing more or less vac and different places that we did not tune for. so in this case i would need to use ego correction maybe.. we found this out by cutting vac to the bov and just driving for 1 hour of tuning with being relay carefully on how much boost i was hitting and to let off slowly if it did hit boost, forgot once tho :O
any ways we could tune shut the car off do what we wanted and all stayed good.
i used my stock FC bov i got from some one in 2006 it's leaking some even im using the plumbers check valve. its still sucking some vac from the bov outlet causing some little lean spots once in awhile at least its just for a blimp and its back to where it should be.
so im going to get a DSM bov at the junk yeard see how that ends up but i do have a line on a greddy bov for cheap so il probly just get that this weekend'
thanks for all your help. btw the ecu never erased its self again after i moved the spark plug wires so that could have caused it to erase its self... who would have figured
