#2680, "Install complete" Oct-23-06 08:00 AM by BlackMagic
Well the megasquirt got installed this weekend! It's still a little rough, needs a lot more tuning, but it's in and it runs! I'm really excited about it. Thanks Terry for building the board, started up just fine. Can't wait to start tuning for some major boost!
By the way the portfueler will be for sale in a couple of days.
#2688, "zeitronix wideband output" In response to Reply # 2 Oct-24-06 11:41 AM by BlackMagic
I know that the analogue output on the zeitronix wideband is non-linear, however I was reading the directions on the zeitronix site and it says that there is a linear output as well.
"Linear Wideband Output (Purple Wire) Zt-2s rev11 and later are equipped with analog wideband output activated through the ZDL software V 2.0.8 or later by selecting 0-5V Linear Wideband Output from the Settings menu. The narrowband output (purple wire) becomes the Linear Wideband Output."
So if we hook the MS up to this wire and change the configuration in MS I'm assuming that us people with zeitronix will finally be able to read actual AFR in the target AF tables. Anyone tried it? I think you have to download the new software from their website first though.

I think you actually need to have the new version, depending on when you purchased the unit itself. Software updates are always available online, but that doesn't change the hardware you have.

#2693, "HORRIBLE cold start" In response to Reply # 5 Oct-25-06 02:33 AM by BlackMagic
This morning the car would not even start, the coolant temp was a little less than 40 degrees. I'm assuming it's not getting enough fuel. From fully cold it takes about 10 cranks to get it started usually but today it just wouldn't go. Someone take a look at my settings and tell me if you did something differently or if something is way off. Sometimes it will crank and start to go to maybe 2000 and immediately die off, sometimes it won't even start up with the crank, other times it might only catch and hop up to 400 or 500 rpms, so I'm guessing there is something wrong with the cranking settings and the ASE settings. And I tried having my foot flat on the floor as well. I've searched through here and tried a couple things xtremers said about richening up the values of ASE to over 100% and if that didn't work using a fixed MAP with my idle MAP value.
I'm using low-z 780cc injectors
Here are some screen shots
Cranking settings
Normal ASE settings
Fixed MAP ASE settings
Someone please tell me I just accidently did something horribly wrong. Besides this starting issue the car runs perfectly fine.

you didnt do anything wrong, its a part of the tuning process. I have never tuned that cold so what you have is a linear slope off the 60 and 80 degree points.
The cranking numbers are to get the car to initially fire. Once it fires the afterstart enrichment takes ofer to keep it moving. Then the warmup kicks in. These numbers will very depending on your ve table and req fuel.
If it doesnt want to initially fire, add cranking pw till it fires. if it fires and dies, add after start till it fires to attemp to run. If it dies after a few revolutions then work with your warmup.

I'm gonna have lots of fun trying to get my car to start when I get my parts in, and have to get it to the Vehicle Processing Center to ship...maybe it will happen to be above freezing a for few days haha.

Yea I was hoping you'd reply since you're from freakin alaska, figured it would get cold up there. I wonder how Corbin is doin, he's in VA and running 780s like me.
