Hey guys running into a weird issue and looking for some advice. Setup is a built lsv, skunk2 pro1 cams, alpha 2200 injectors, m and w pro 19 ignition, all supporting mods. When I first start the car, it seems to warm up super lean like not showing afr just pegged lean, then the second it hits 180⁰ it reads good afr and idles like it should. It doesn't seem to matter how much fuel I add to the coolant comp table, and I'm not sure what else it could be. Dead times are correct, I was wondering if there might be some kind of ignition comp that I'm missing, or any other suggestions to get this thing dialed in. Thanks all!

Post your calibration

ok I'll get it posted in the next day or so thanks

Here's the calibration file

What fuel pressure are you running with the key on, or running with no vacuum hose attached to regulator? The dead times look very low for those injectors. I assume you have a wideband wired to D14? You should use the ELD input and remove R136 and R138. Can you post a log?

60 psi base fuel pressure. I used the dead times provided with the injectors. I use d14 yes, but it reads just fine once the car hits 180⁰ so I'm not sure why that would be an issue. Can you elaborate? I can get a log tomorrow morning for you.

D14 limits voltage both high and low. You won't get the full reading of the wideband, may only read down to 12.5 and up to 16 depending on what your using. D10 allows full 0-5volt to be used. I was looking at the dead times for Grams 2200, my mistake

ok good to know...I know it's past the 16 afr limit....then like I said as soon as it hits the 180 mark and runs off the map it runs great. I'm missing something stupid.

Try this, post a log of this from cold to 190 water temp if you can.
