please help i suck at MSPNP
 

At this time i have finished with the mechanical part of my car. I know have to deal with it electonically. The problem i am having is that its completely fine while idling ( sometimes ) and when driving it gets suuper lean to the point of bucking. It goes past my boost gauge. While at a standstill and revving it gets real rich for periods. Im using AEM Eugo wideband. Any insight would be greatly appriciated. BTW im still super new with MS :noob:

Should i take a datalog of this?

i fucked up i cant find my MSQ files :facepalm:

I think something might be screwd up. I reloaded the base map and now it runs like poop even after i changed the injector size (maybe its an exhaust leak but it sounds lame)

Did you RTFM? By the sounds of it, you've got some major reading to do...

To start, you may want to read up on Joe's thread about using AFR instead of Volts with the AEM wideband.

If I were to venture a guess, which is all I can do at this point, it sounds like you need to change your config settings for your wideband and map sensor. You may have already done this, but again...just a guess.

yes i did AFM delete. And i tried changing it but i cant open a new msq with it active

Also i changed the config for wideband. It shows up in megatune

If it gets "super lean to the point of bucking", you probably need more fuel.

Take a long datalog and try to hit every point on your fuel map, maybe stay out of boost for now. Run that through the MLV (mega log viewer) and get the drive ability in check.

Try re saving your msq in megatune and posting it here. (make an msq folder and throw it on the desktop so you don't loose it, inside that folder i suggest making another specifically for dataloggs)

Just pulled the spark plugs. 1 was completely dry while 3 where soaked with fuel. All 4 plug wells have fuel on top of the piston. Im afriad i might have fouled something up. Last time i tried to start it it wouldnt even catch and made a CSHHHHH noise wich sounded like the starter was stuck or something. Im not sure if maybe i should cut my losses and take it to a shop.

figured out my msq. Check it please!

Post a log too. I wanna see what your IAT and EGO corrections are doing.

I dont think it will run

Do you have injectors leaking into the cyls?

I'm at work right now but i'll take a look at your msq when I get home this afternoon. I'm going to be near by this weekend but i'm really unsure if i'm going to have enough time to come help you. I'll be working at Pacific Raceway all day sunday.

Do you have a Mapdaddy sensor?

Is the map signal line plumbed in correctly without any kinks or pinches?

Your Cranking Prime Table looks off to me. So does the the REQ in Engine Constants, and the pulse width. I have the RX7 460's and maybe this will help.

Try adjusting the PW back to 1.1 or 1.2. Set the REQ at about 7.5 or so.
Cranking Settings...
20F-6.2
40F-5.5
60F-4.9
80F-4.1
100F-3.2
130F-2.5
160F-2.2

Hope this helps some.

My I have RX7 460.s

the MAP line is plumbed and posts readings fine, no kinks

How do i check if i have fuel leaking into the cylinders? Could one of the injectors be malfunctioning?

Not sure what the "Mapdaddy" sensor is. I have a basic MSPNP90-93 with latest factory specs. Any way to check if i have one?

Thanks for some values. Although i dont think this is the problem. I believe it has something to do with not correcting AFR via wideband in relationship to Map changes.

An MSPNP-MM9093 would not have a MapDaddy unless special ordered with one. MSPNPs with the MapDaddy can be recognized by the barbed fitting poking out the side of the case.
