I have a 99 Eclipse GSX with a 7-bolt motor no balance shafts and I just redid my timing belt because I noticed that the tension was off and it indeed had the wrong tensioner installed. I got it all put back together and running again.

Although I got it running, the AFR gauge was reading lean. So I figured I need to double check everything including the timing and what not.
I have a 1g CAS installed with the correct harness, also checked to be sure the CAS wasn’t 180 out. The car is indeed timed correctly, I triple checked that part before installing the timing cover.

After I adjusted some settings in link my car will not start now. It'll try but no luck.
I'll post a log of it trying to start.

Mods List
Stock 2.0 7bolt with 1g CAS
Knockoff Tial BOV
Evo3 intake w rebuilt NT TB
t4 top mount hx40
Speed Density
Stock ignition
AEM X series wideband
Front O2 simulated

FUEL
e85
-8 feed -6 for return with Hellcat 525 pump to 2150cc FIC
Fuel lab fuel filter

Thanks, Mike

Edit: I loaded up my previous log from my other motor since it's basically the same setup.
The log I'm attaching now is from today and the car starts right up but just goes lean pretty quick at idle.
I want the car idling pretty good before I take it on the road and go from there.

Steve! I adjusted that. My tps threw a code and I adjusted the sensor. It may be time for a new one or double check wiring but it's working now. I triple checked boost leaks as well and I'm running an EBC to 2 external wastegates.
Let me know if you see anything else out of the ordinary ?
I'm sharing my most recent log of it running 16% tooo lean as I do not have a log of it idling around 14.7-15.5, I forgot to do so last night.

You're lean. And on top of that, your SD table is over inflated across the board. This is going to be corrected correctly using deadtime, but first things first:

Load in a "stock" SD table.
2150s really flow closer to 2200. 450/(2200*.65)-1.0 = -68.5% global fuel setting for e85.
Put deadtime on the fuel tab at 0.
In direct access, go to InjBatteryAdj and change the values to below. This shape is the personality of 2150's. These values should be changed and forever left alone.

7v -> 2295
9v -> 1421
12v -> 939
14v -> 749
16v -> 555
19v -> 495

When all of the above is done, start the car and let it fully warm up. Then, change only deadtime on the fuel tab up or down until your wideband reading = afratioest.

This should leave you with a well behaving car, accurate airflow, and have you in a good place to headache-free calibrate the fuel system.

I appreciate that man! My car would only like to start with v7 at 1853 and global fuel set to -60.9%.
I'll change the VE table back to stock. and InjBatteryAdj settings back to what you said and see if it'll run. Base fuel is set to 43-43.5 ish

Ok so The car only seems to start and run at global fuel:-60.9% & I changed my AdjBatteryAdj Volts to the settings you gave me and VE table back to stock.
I changed deadtime to around +215 and AFR seems to be around 14.7 but CombinedFT still isn't 0

15* timing at idle is very high IMO, and it fluctuates up a few * higher from there. I think this is causing your idle to be higher than target and possibly kicking you in/out of closedloop.

With the key-on or engine running I would go up to ECU>Reset fuel trims, but CombinedFT is not a tool I would be using for this situation.

I'll get timing adjusted correctly and everything else and I'll come back with another log of it idling for awhile. Thanks !
