Re: "Block Learn" vs. "Intergrator Value"?
Xfire,
Thank you for the light! Okay so if I'm understanding this on a beginning level then: Open loop uses a pre-programmed table of fuel based upon MAP & TPS feed back...chit forgot water temp & air temp, right? closed loop is what has actually happened as reported by the O2 sensor (results of combustion, good or bad A/F ratio. ), and MAP & TPS & IAT and Knocks..?...modify that ratio dictated by O2 results? Jezzus, O2's are the main player and the rest of the stuff is secondary data inputs...I'm wasting your time, I apologize. Somehow I get the feeling that I'm in need of some basic text books on EFI so I can start at the beginning! Thank you for the start, I do appreciate it! Tom

Go here for a real wealth of information on tuning and how ECMs work. http://www.thirdgen.org/techboard/di...uide-book.html One thing I really like about 3rd Gen is that it is a community that shares information. Everybody helps out everyone else and there are many very knowledgeable people on that forum. The Buick GN forum is the same way. These are all people that have had to do it themselves because there was so little support from the aftermarket on TBI systems primarily. The 3rd Gen community operates on the premise that the more everyone knows and understands the better off everybody is. The concept of holding back information from the community "for your own good or you'll screw something up" isn't one that's accepted on that forum. Plenty of warnings and info, but nobody is trying to be your parents. Quote:
The VE table is usually a 3D table using RPM x MAP to specify the amount of fuel to be used. So its always using MAP sensor input but not the modifiers. If tuned correctly the value in any particular cell should get you close to a BLM of 128 in C/L. If you're using O/L, you want to shoot for 14.7:1. But its not necessarily true that if you tune the motor in O/L to 14.7, you'll be at a BLM of 128. The two aren't necessarily the same value. I won't explain that now because it gets into O2 sensor voltages and stoich setttings etc. in the cal. Quote:

Re: Fuel injection basics
Tom,
One of the best books I ran across for anyone getting their head around (Corvette) fuel injection for the first time and the role of the ECMs is "Corvette Fuel Injection & Electronic Engine Management" by Charles O. Probst, (ISBN# 0-8376-0861-9) It starts w/ the basic premises, and then goes on to specific engine descriptions including: L83 L98 LT1 LT4 LS1 LS6 LT5 This book doesn't go into ECM code manipulation, but rather all the basic concepts are introduced making the transition easier. And, it is just plain fun to read (in a geeky sort of way! Well...After Pete's Midwest BBQ last night at Marc Haibeck's shop, I'm intrigued and will be looking for an "Ostrich" here pretty soon. It might be interesting to start a bulletin board w/ some favorite "hit tunes" that can be downloaded. Thoughts for another post. P. |

Re: "Block Learn" vs. "Intergrator Value"?
Ive been following several threads re code scanners and data manipulation....but am a complete novice
And l have been thinking of shipping myself over to the US for a ZR1 holiday at gordons school.....the full set of courses is data logging and manipulation covered by Gordons school or is this a subject you pick up over the years.....(and at my age l could be dead before l learn this stuff) |

I think to understand why the calibration is what it is, you need to have an understanding of EFI and ECM controls. My suggestion for those of you interested is to visit thirdgen.org in the DIY Forum. Lots of stickies on tuning and understanding the basics. |

Re: "Block Learn" vs. "Intergrator Value"?
I also have the AutoXray 1000. I need ot become better acquainted with it and reading the values. It seems slow and limited on the amount of time for it's dialogging feature, but it is better than nothing. I also have the CD for EZ-PC connection and having problems getting a printout that matches the screen graph, does anybody else have this problem?
