LSA conversion problem

[FieroItaliano85]

I installed my new tune after I did the LSA conversion yesterday. It runs great for about 5 seconds. Then the car runs very rough but I get no check engine lights. The car will not respond to pushing the throttle down, it just makes the car bog and want to die out (sometimes actually does). Has anyone experienced a similar issue and know the fix? Everything is installed where it should be. I emailed my tuner a data log of what it's doing just waiting for an answer. Any help would be great.

Verify the tune first. Did you install anything else at the same time? Did you get the plug n play connectors or did you solder the wires? Are you sure your getting enough fuel?

Double check and make sure no vacuum leaks also...

3 COMMON MISTAKES

1. Customer has ZL1 Map sensor in use and the tuner did not make the proper changes to the cal for this sensor, or just the other way around.
2. Maf is installed backwards.
3. Wrong map sensor plugged in,The barometric sensor is in the lid forward driver side as is open to the atmosphere,take it out and sell it on ebay

They were plug and play, we did have to soder the wires tho. It is getting enough fuel for sure. I don't believe any vacuum leaks either.

The zl1 map is definitely plugged in. I'll double check the maf but I'm pretty sure that's correct. I have my tuner checking into the issue. Just wanted feedback from guys who may have encountered a similar situation. Thank you! I'll look into these matters
