andrewb70 Apr 27th, 11, 2:11 PM Nice, but needs more cold start-up tuning ;-) Andrew swcash Apr 28th, 11, 2:46 AM Very nice. Is that a 2000 cfm throttle body? Squido ss396boy Apr 29th, 11, 2:22 AM Nice, but needs more cold start-up tuning ;-) Andrew Suggestions on where to start? Noob here. Was going to try to find a base number and change the entire VE table until it warms up. Very nice. Is that a 2000 cfm throttle body? Squido nope only 1350cfm.. Doug F. Apr 29th, 11, 7:52 AM Don't change the VE table UNTIL it warms up, unless the car won't run, then you have to. Likely you have to richen it up. It is lean right now, as well as may not have enough air at idle. Likely just lean. Get it warm, adjust the VE. On next cold start THEN adjust coolant/afterstart enrichment. ss396boy Apr 29th, 11, 12:15 PM Don't change the VE table UNTIL it warms up, unless the car won't run, then you have to.

On next cold start THEN adjust coolant/afterstart enrichment. I have the blades cracked @ 4% right now but the IAC sounds like Hoover vacuum. It eventually cuts out after it gets warm for a bit. I enriched it @ 3% at that temp and that seemed to help smooth it out(not in this video) Thanks Doug... I'll give that a try. Hoping to get it to idle better this weekend. vrooom3440 Apr 30th, 11, 11:02 AM "IT'S ALIVE!" You actually got that thing to run finally. I was wondering the other day if you ever got back to it or if it was just going to be another forgotten pile of parts in the garage. You need to buy a book to walk you through the tuning process. You understand working with computers: if you approach it methodically and climb the stairs it is not too hard. But if you just start doing random stuff things will happen and you will have NO idea why. Just like S/W testing :D ss396boy May 3rd, 11, 1:29 PM "IT'S ALIVE!"

It's all connected the same way, except it works now. Process of elimination, doesn't help when you send parts in for repair and they send both back not working. :) mad rat 454 May 30th, 11, 2:56 AM you need a CARBURETOR! ss396boy Jun 6th, 11, 4:35 PM you need a CARBURETOR! It's ok to be jealous. ;) Runs a bit better now... YouTube - ‪540ii‬‏ mad rat 454 Jun 6th, 11, 6:40 PM its a very nice set-up. I can appreciate your time and effort. . . bikeron Jun 9th, 11, 11:01 PM Looks good... Sounds great.. Ron 67 velle Jun 14th, 11, 9:06 PM How big is the cam ?It idles good. I have a 540 xfi too. I'm learning on the fly tuning, and you only get so much from a video. Having said that, it sounds like you need to increase the fuel table AE Fuel vs TPS Rate of Change. This acts like you accelerator pump in a carb. Makes it rev quicker when it's set right. Also throttle follower setting in idle section needs to come down some. This is the high idle after realeasing the throttle. Again only trying to help. LevonH Jun 14th, 11, 10:21 PM Hi Jason. Can you check your coil connection ? It appears that MAYBE the + and - are reversed. It may just be the picture???? Orange from the MSD is + ss396boy Jun 15th, 11, 2:24 AM How big is the cam ?It idles good. I have a 540 xfi too.

Yep, I still have lots of tuning to do. Thanks for that tidbit though. The first video I had the timing locked out so it didn't rev very well. Cool thanks for the info, i'll check the throttle follower. I'd be interested in seeing your tune file as well. | ||
