[QUOTE="365 Saleen, post: 16821517, member: 201889"] A number of little things. The amount of fuel enrichment during cranking. The whole fuel table was revised and the system just needed to sync. The cam and crank sensors were not synced. It was not that they were out of adjustment, they just needed to "see" each other for longer than a 5-10 second crank time. This was accidentally found out when just for shits and grins he recommended that I spray a bunch of Brake Cleaner down the throttle body. I did, cranked the engine and it lit off and ran for about 5 seconds then died. A minor adjustment to the start fuel table and it lit off and idled on the next start attempt. I still have some adjustments to do, the O2 sensors are only 8" away from the end of the header and are getting diluted readings because of it. He recommended that I install some 18-24" long header collector extensions so that better adjustments to the idle table can be made. Once that is done the extensions can come off. Problem is, my header collectors are 4" in Dia. so getting 18-24" long 4" diameter pipe under the car may be a challenge. Also the engine idles at 1,500-1,600 rpm and I did not have the proper allen wrench to make an idle speed adjustment. It typically should idle around 1,100 rpm. I am not using an Idle air bypass, so the idle is controlled only by adjusting the throttle opening. The whole process took about 3 hrs of real time. He used Team Viewer so he could control my laptop and we were on the phone the whole time. When the engine lit off and ran on it's own the first time I shut it off after about 20 seconds because I could not hear if he was saying anything. Lol. I took video with my phone but the sound is so loud the phone could not process it, it is just a bunch of garbled noises.
