Still don't know about the port issue. I'm using a performer rpm manifold and everything looked like it lined up proper. Yes, full rollers, tall valve covers. No egr. Was your "adjustment"...

Okay, time to move this one back to the front burner. I have run across an accel dfi setup and wanted to know if you thought this was better than tbi or overkill for my mild combination. I don't...

Thanks for the info. The only thing I'm dead set on, is getting this combination of parts right. If there's something that I can change now and avoid headache latter I'm all for it. I just measured...

Okay. Did a search on comparisons with no luck. I'm sorry, I just like to know why something is different or better. It's been a few months now but I remember measuring both and seeing a touch...

Tom, thanks. The heads are ready to go. I have the throttle body off of the ,sorry, 92 not 94 454. Picked up the holley real cheap and saw that the bores were larger than the gm. So stock would do...

Yea, I know in the big block world that cam is very mild. Shortly after I built the motor I found someone who had built an almost identical set up and compaired that cam with the 60202. It had more...

Hey guys, been a while since I've posted. I know I'm prolly gonna get flamed on this one but I've built a 454 for my sons 95 ECSB OBS. I've got pretty much everything done except for paint and...

Pm sent

Thanks for the feedback. I kind of thought with the temps down here it wouldn't be too much of an issue. Also with the big block generating a little more heat. I thought the dual plane would lend...

Just an up date on idle mode. I bumped TPS% for idle up to 3% from 1.17 and haven't had a problem with staying in idle mode since. My BLMs are consistent 27-28 cruising from off idle to 75 on hwy. ...

Like title says. I've heard it said that intake will run too cool causing hard time tuning idle. I can pick up a damn near brand new one for $75 near the house. This will be on a stock bore 454 with...

Never mind the request, finding plenty info out there. Google is my friend!

Chris.

I understand blm and int are short and long term. What I don't know is the meaning of cell boundaries. Can you point to some threads that explain this in depth? I agree with Map threshold for idle...

I see that you changed the blm cells more around my idle. Would you explain those two as there is no parameter comments for them.
Chris.

Thanks, ill take a look. The motor is totally stock except for cam wich is probably overkill. .216 .223 @ .050. I know mechanically its solid with new everything except knock sensor and esc mod. But...

Anyone else have an idea what to look for? Everything I see in datalog is shows it should be in idle mode but its not. When it does go to idle mode the IAC drops down and runs about 700 rpms. I've...

Cleared codes and went for warm up drive. wasn't idling as high but still no idle mode.

Chris.

It's scalar IAC - TPS percent for closed throttle

Sorry, I did not see that. I guess I just thought no check engine light= no codes. I'll take care of that, thanks.

Chris.

So then the 1.17 is volts and anything under that with no speed should put me in idle mode?

Chris

Okay, scratch that. I must have some how keyed that in when I pulled it up. I went to close the window and it asked to save change. I said no, reopened and it's set at 1.17. So it looks like I...

Like I said, my Tps will set on either 0 or 1, so I don't think it zeros out. In fact, after setting my min air I had to move my TPS. I enlarged the holes not enough the first time and went back to...

Started with stock ASDU from this site. I thought that under a certain Tps, like 1.1.......Holly %@#&! I think I may have found the problem looking to tell you that value. How about "IAC TPS...

This one is driving me nuts! I've been working on getting my VE table in line and making good progress but my idle will sometimes be ridiculously high when I come to a stop. I've just noticed today...

Thanks six. Was wondering if that was required or not. Is there a minimum time I should wait or just unplug and plug?

Chris.
