[Msnse L28et Freeway Excel Problems]

You know... I was never really sure how to do this and I think the way you did it is right. Itired to do it that way but the only way I could get the LED to go on was to have the DIST. fully retarded. I probably have the oil pump shaft off or something.

 

I have not ran my car with the changes yet but I think I'm going to right now just to satisfy my curiosity to whether or not I found my problem.

 

Be back in a minut! If you see a cloud of smoke on I-5 It's probably me. HAHA:fmad:

let me get this right... so when you are doing your timing, do you have the timing light on the #4 spark plug? cause that would be the one prior to #1 according to the firing order. 1-5-3-6-2-4. And if so is your DIST. set all the way advance (clock wise) or retard (counter clockwise)?

[Msnse L28et Freeway Excel Problems]

OK OK OK! I think I figured it out reading my own post. Setting the distributor fully counterclock wise sets it at full RETARD like me!

 

The more and more I thought about it...I wondered how could the MS retard timing at high RPM if its already at full retard from the begining.

 

So, I set my #1 CYL at TOP DEAD CENTER and set my DIST. till the center LED on my MS lit up. I then locked the DIST.

 

Started the car up and the RPM was at 600 idling and not so great. I set the FIXED ANGLE on the MegaTune at 10 degrees BEFORE TOP DEAD CENTER and got my timing light.

 

From their I fully advanced my DIST. and locked it down. I then set my TRIGGER ANGLE (DEG) on my MegaTune to 81 to compensate for my full advance DIST. It now reads -10 on my MegaTune and -10 degrees on my crank pully using the timing light.

 

Only thing now is at the 0 DEG mark I unlock the DIST. and move counterclockwise to fullclockwise and the LED on the MS wont light up. So I just set it back to full ADVANCE locked it down and it still started up nice. It even has a steady idle at 800 RPM.

 

I just have not gone out to see if that would die at full TP on the freeway, Its like 1AM.

 

I'll post up later to let everyone know if I was just an Idiot. But before I do... did you guys agree with the prior DIST. timing being wrong?

Braap,

 

Thanks for the heads up... Sorry, I'm used to writing in capitol letters so I type the same way too. I'v been so used to it after writing police reports for 8 years. It was just considered more legible... than lower case.

 

Sorry bout that guys! Anywho, I'll send you my log as soom as I figure out how to get it out of my stoneage laptop. No CD or DVD writer!

 

Oh I also forgot to mention after driving it to work a few days ago, I resetted the MSI during my lunch by opening up the program again burning it and of course turning the ignition key on and off. The MSI ran a lot better on the way home but the Log reads as such:

 

Steady 70MPH / FULLTHROTTLE

 

Gve 55 / 76

PW 4.7 / 14.6

Duty Cycle1 13.3 / 42.6

 

RPM 3403 / 3500

MAP 42 / 105

TP 7 / 25

 

O2 0.804 / 0.000

FuelPress 3 / -7

EGT 101 / 50

 

pulseWidth2 4 / 14

MAT 46.1 / 46.1

CLT 98.9 / 97.2

 

As you can see... well maybe not but the o2, fuel press, egt, all drop I put these three in graph 3 together cause they all seemed to drop upon putting the pedel to the floor. I figured this out by going down the list and saw that these three seemed to all run parallel to each other and all do a vertical drop at the same time. But the difference is the pulse with did not drop like it did before I re-burned the MSI. But still the same thing the car stops when the pedels down to the floor.

 

My first thoughts over flooding or even raw flood mode at tp setting too low. or even ign problems. but with the ign why would it contiue to run after letting off the pedel? MAN what ta head ache!!!

 

So anyway i know it worthless without a picture so ill send it to you asap.

thanks

BRAAP

 

you guys are awsome:icon6:

[Msnse L28et Freeway Excel Problems]

HEY RON... HOWS IT GOIN? SORRY I DONT UNDERSTAND WHAT YOU MENT?

 

"First, some respectable people are trying to help you and you are talking 'at' them. Chill, my friend."

 

DID I DO OR SAY SOMETHING WRONG??? SORRY IF I OFFENDED SOMEONE BY SOMETHING I SAID OR SOMETHING I DID...

 

ALSO I DONT KNOW HOW TO SEND YOU A SNAP SHOT OF WHATS GOING ON, ON THE LOG. IS THERE A WAY TO SEND THE FILE?

 

MAYBE I CAN SEND IT TO YOU VIA EMAIL?

THE MSI WAS MADE BY RS AND HAS THE HI IGN OUTPUT.

 

 

 

ALSO ANOTHER THING I NOTICED ABOUT HIS SETTINGS ON THE BAROMETRIC CORRECTION WAS WAY OFF FROM WHAT

 

MY MAP IS READING (61 KPa) ATMOPHERIC PRESSURE IN CENTERAL CALI. SO I CHANGED IT TO MAX 55 AND MIX 65

 

 

 

BAROMETRIC CORRECTION ON HIS SETTINGS WERE:

 

MAX Kpa FOR BARO CORRECTION (KPa) 116

MIN Kpa FOR BARO CORRECTION (KPa) 67

 

 

THANKS GUYS

[Msnse L28et Freeway Excel Problems]

THANKS FOR THE INPUT GUYS... SORRY I DIDNT GIVE A LOT OF INFO! I DIDN’T JUST THROW THE MAP IN AND JUMP ON THE FREEWAY AT FULL THROTTLE, ALTOGHT THAT WOULD HAVE BEEN FUNNY IF IT DID BLOW UP IN MY FACE.

 

NO REALLY, ITS COOL CAUSE IN THE CALIFORNIA CENTERAL VALLEY THERES A LOT OF COUNTRY ROADS WITH LONG EMPTY STRECHES SO I HAVE BEEN TESTING IT AT LOW, MID, AND HIGH SPEEDS. EVERYTHING FROM SLOW EXCELERATION TO FULL THROTTLE NECK SNAPPING TAKE OFFS FOR ABOUT A MONTH NOW BEFORE GOING ON A FREEWAY.

 

MIND THAT THE CAR I WARM AND RUNNING BEFORE THE TESTS BUT AFTER A HARD DRIVE THE SECOND RUN WOULD START DYING AT FULL OPEN THROTTLE JUST LIKE ON THE FREEWAY TOO.

 

I EVEN LOGGED IT, AND WATCHED IT ON MegaLogViewer IT SHOWS THAT THE FUEL PSI DROPS ALONG WITH THE INJ PULSE, AND THE O2. ALMOST AS IF THE SOME ONE TOOK THE BATTERY OUT OF MY CAR.

 

TRUST ME IV TRIED TO AVOID ASKING FOR HELP JUST TO SAVE MY @$$ FROM BEING STONED AND CRUSIFIED FOR SOMETHING I MIGHT JUST BE OVER LOOKING.

 

I TELL YOU THOUGHT THIS THING SPINS TIRES AT 6 PSI AND EVEN CRAZIER AT 13 PSI. IT’S JUST THAT IT GOES DUMB ON AN ATEMPED FAST EXCELLERATION AND AFTER ONE HARD RUN.

 

I DUNNO I GUESS IM AT A LOSS UNLESS I CAN FIND ANOTHER Z GOER IN THE CENTERAL CALI VALLY:sad:

[Msnse L28et Freeway Excel Problems]

I have a MSNSE program from another hybridz go-er it actually runs really well but on the freeway after cruising for a while i would try to excel and the motor will stop running as if the motor died. So I would release the pedal and the motor would continue to run as if nothing happend.

 

I would then stab the pedal all the way down and it would die. Id even hold the pedal down for about 5 to 8 seconds and it would just coast as if the car shut off. Then I would let go and the car just keeps on running like nothing happened. All I could do is drive at a steady rate without acceleration.

 

The only way I could accelerate is to press the pedal slowly and let it climb speed little by little.

 

 

HAS ANYONE ELSE HAD THIS PROBLEM? I CANT REALLY DO A SERCH CAUSE ITS TOO SPECIFIC OF A PROBLEM. ALL IV BEEN DOING IS GOING PAGE BY PAGE ON THE MEGASQUIRT FORUM WITH NO LUCK.

 

DOES ANYONE HAVE A RUNNING PROGRAM IN CALI? CAUSE I KNOW THE ALTITUDE PLAYS A ROLE ON THE MAP.
