Here I made some needed changes for your startup and I also fixed a few of the inputs [AC idle up] that would have not worked otherwise.

Review the changes, on first start the car may be rich or lean dont freak out. Open the VE1 table and start to adjust the fuel, lower numbers reduce fuel higher numbers add fuel. You will know where the fuel needs to be added there will be a blue dot running around in the tables once the car is running, this dot is where the engine is pulling its info from.

@a91what awesome thanks! Once I get it going I’ll report back!

Thanks!

One more quick question...for now anyway.
Currently i'm running about 13/14 deg timing with spout removed. When setting the timing in tunerstudio and trigger offset do i leave the current settings where they're at, fixed 20/offset 14 or should those starting points be changed before i proceed?

change your base timing back to 10*.

OK guys i got everything hooked up and it fired right up and idles better than before. My issue is i don't think i'm getting correct afr readings? it seems to hold rock solid on one number. i would think it would fluctuate. I data logged and attached below.
I'm going to recheck all my wb controller wiring.

Well the car did very well for a first start!!! the wideband is not giving a usable reading something is amiss with your settings

Checked over my wiring and grounds. I’m getting power to controller when running. Could my jumpers be wrong? I posted a picture of them earlier in the thread

did you go into the tools menu and calibrate the WB in Tuner Studio??

No sir! I was just reading in the manual and found that section and will read it. Any tips or is it straight forward?

Its easy, use a "custom linear WB" and setup the simple 4 entry table with the AFR vs voltage in the instructions that came with the WB.

There was an option in the drop down for the 14point7 spartan controller that I have. I selected and wrote to ecu but it’s still not reading afr

Did you by chance accidentally wire in the narrowband wire??

a91what · Jan 12, 2019

also look here for detailed instructions. https://www.14point7.com/blogs/news/16539352-maximizing-accuracy-between-spartan-2-and-megasquirt

No it’s the green wire. I made the intial wb settings they posted in that article and I’m still not showing a proper afr reading. Did you look back and see if my jumpers are correct?

KZGUNS · Jan 12, 2019

While idleing im getting 2.33v on the green signal wire going to ecu from controller

a91what · Jan 12, 2019

did you remove the J6 jumper??

No. I assume that’s my issue?
I’ll do that and report back!

KZGUNS · Jan 12, 2019

@a91what removing jumper didn’t change anything.

KZGUNS · Jan 12, 2019

If I unplug the expansions plug from ecu the afr drops off. So it’s getting a signal. Bad controller? I get a solid 2.33v from the green wire while running. I would think that should fluctuate as it’s reading afr.

Talked to 14point7 after a few tests they think it’s a bad controller and will be shipping me a new one on Monday. For what it’s worth they were very helpful and answered the phone everytime I called back with test results. Great customer service.
