Probably timing, get a timing light in there and verify things per the manual.

It ended up being the laptop had a virus and was screwing up tunerstudios settings. I reset the firmware and used my destop computer with extended com port and once everything was reset it started perfectly.

Are you sure it is a virus and not just corrupted firmware?Toyota20R wrote:It ended up being the laptop had a virus and was screwing up tunerstudios settings. I reset the firmware and used my destop computer with extended com port and once everything was reset it started perfectly.
My very first install drove me crazy for about two weeks, it turned out the firmware was corrupted.
I reinstalled the same firmware and everything worked fine after that, just a thought.
