Well, looks like a little tuning of the VE table(s) is in order. Where ever the BLM is less then 128 is too rich, so lower the VE. Anywhere the BLM is > 129 is too lean and you need to increase the VE.

The last couple of tables give the correction factor. Mutiply the VE term at that location by the correction factor for the new VE term.

As far as to the whole meaning of wide vs. narrow I have no idea. The WinALDL site and/or doc should help with that.

man i would think that with my setup i would be able to use all the fuel in the stock programing. dose this mean that all my work was for nothing

i have a holley 670 tbi, projection intake, headers, compcam xe249h-12 cam, full flowmaster catback, and a 14X3 K&N filter. do you think that with the stock heads it just isnt able to make any more power than stock LO5

 

whenever you change the airflow potential of a motor, you are going to have to change the fuel maps, plain and simple.

changing the throttle body/TBI, intake, and the entire exhaust system, will certainly change the airflow potential (after all - that's why you upgraded all these parts, right?) - so now you have to tell the computer that you're flowing more air.

also note that since you changed the TBI, you probably have different size (lbs per hour of fuel flow) injectors, so that requires a little bit of tuning too.

it looks like you are almost universally rich, so I'd hazard a guess that you switched to bigger injectors.

the good part is you haven't changed too much, injectors and intake/exhaust are pretty easy to tune for. first thing first is to correct the injector constant (or the equivalent of the injector constant in whatever code/ecm you are running), then start roughing in the VE tables to match your combo. increasing the injector constant/base pulse width (whichever your setup uses) will get the lower end stuff back in line, and then you can work with the ve tables to get the high end stuff back in line.

...at least, that's how i'd do it.

 

i think i herd that the holley unit uses 65 pph units.

 

the way that i was thinking was that after all the mods air gets in beter that would make it go lean. but with the 65' s in place of the stock ? 55's ? it made it go rich. pluse the cam and the beter intake would that make it have less vacume and cause the motor to dump more fuel un neededly

 

With the mods your changing the powerband of the motor. The relative VEs will be less then the L03 at low engine speeds and higher then the L03's at higher speeds. Itll be rich down low, and possibly lean at higher rpms and loads

 

With the stock heads you probably wont be able to make much power. Should be able to make some decent torque, though. I have a similar but less agressive grind in my 350 and it has insane throttle response and some torque with the small runner heads, dual plane, and dinky *** headers. Probably a good set of heads to go along with that would be a set of mildly worked over 305 TPI heads or similar small runner heads.

I wouldnt pass judgement on it too fast. The performance should improve as you get stuff dialed in.

 

I think narrow tosses extreme values to either side of 128 out. I would have liked to see an option that displayed the mode instead, though. I think it would have been more useful.

 

how do you tell the mode do you do that by recording the flag data. also i now know that i am going to have to get into prom burning. how much am i missing out on with the programming as it is now. i would love to hear that there is a bunch of untaped torque that i am missing if so how much you think thank you for all the help now just to find a new programer and hop it is not broke when i get it like last time

 

Tuning EFI is amazing.. The wrong tune can put a 500hp street/strip car into valet mode.
