I can give you the tune, can't get a log for the above reasons, though I haven't gotten the datalog to work forGet me a tune and datalog file of the car running.
Big thing is why is the laptop disconnecting.... I have a few methods to try and connect to remedy this.
Few basic questions for my inquisitive mind.
- true iac or a warmup valve
- have you tried unplugging the iac to see what happens.
- verified that the TB is not stuck open some.
If nothing happens with the iac unplugged then it's not the idle settings.I can give you the tune, can't get a log for the above reasons, though I haven't gotten the datalog to work for **** anyways.
Nothing happens with the IAC unplugged. I've gone while the car is running and physically shut the TB by hand. It idles down to probably 1500 all the way against the throttle stop.
Car idled at 900 when the coil packs were all screwed up lol.
It'll try to get that stuff together. Hoping the laptop disconnecting is voltage drop from a battery that has been in a cold garage all winter
I removed the intake and checked it. No cracks. Really snugged it up upon reinstall as well. I had hoped that was it as I would have used the excuse to upgrade.If nothing happens with the iac unplugged then it's not the idle settings.
With what you have described I think it either has to be a mechanical failure (cracked intake) or you have too much timing in the engine at idle. Timing REALLY affects idle speed.
The MS is connected directly to both posts on the battery.Try running a wire from the battery straight to the MS. I had a problem with my MSPNP2 disconnecting and found a loose connection in the power feed to my ECU. Steve was a huge help....my car wouldn't start at all. Now it runs and idles.
This system is one of the best but it doesn't calculate itself for you. There is a learning curve for sure. This set up works great once the basic settings are correct. Theres a lot of toying with required fuel and WUE. My car is almost there.
don't let frustration get the best of you....I guarantee its something simple and MS doesn't have anything to do with your problem.
I just downloaded the ms3x firmware so I can get myself accustomed to it before we have a "meeting"....I removed the intake and checked it. No cracks. Really snugged it up upon reinstall as well. I had hoped that was it as I would have used the excuse to upgrade.
Nothing changed with th IAC unplugged though dropping the warmup duty from 90 down into the 50s seemed to lower it. I could have just been hearing what I wanted to though. I kept screwing with IAC settings and looking through Ms forum posts but wouldn't start at all towards the end. Think the battery ate it.
I've got it on a trickle charge, will try it again in the next couple days.
I'll post the timing table and msq here shortly.
It's literally just the tune they emailed me with the injector size and cubic inch changed. Tried to eliminate as many variables as possible. They sent me a stock 4.8 tune and an "ls1 big cam" tune.
I'm not off til next weekend. I'll shoot you a text.I just downloaded the ms3x firmware so I can get myself accustomed to it before we have a "meeting"....
This system has everything, I am very jealous..... I mean they even included a setting for anti-lag... blended tables and full independent cylinder trim... not just fuel but timing, ego control... I can see how this firmware can be daunting to the uninitiated.
When you are ready to play with the car again text me I believe I gave you my number.
You put much faith in wideband readings at idle? Always seemed inaccurate to meTry this tune out. All I did was tweak some of the tables and settings for you. they have implemented a new idle fuel strategy, I will need a datalog and AFR reading from the car before I can adjust the fuel tables.
I give wideband readings at idle little-to-no value usually there about two points off on the lean side. I adjust fuel at idle until the car feels good and starts making more vacuum. However being that I'm hundreds of miles away on the other end of an electronic device. it's the only viable information that I can use. I need the AFR readings for quite a few things the datalog will show me vacuum and whether or not the idle is oscillatingYou put much faith in wideband readings at idle? Always seemed inaccurate to me
Forgot to add I really appreciate you looking at it, can't wait to give it a shot
I like it
The day hell freezes over and it actually moves under power.When will we see passes in this thing?

I thgouht you said the car hasn't seen the light of day? Then, how did a bird crap on your mirror then....?
