tuning ls1 nova track car

[speedyblue]

hi, i was wanting to get some opinions i have a 1962 nova that has a 2001 ls1. right now i am learning to tune using v1. my car is only used on the dragstip. would you guys recomend trashing my maf and doing a olsd tune or keep the maf. i am having trouble with my maf table and thinking it would be easier just to
keep an eye on a sd tune. any ideas or opinions

speedyblue,

Welcome to the forum...

Do you have a wideband O2 sensor...?

Have a read thru the AutoVE tutorial:

Just set your target AFR in B3605 and B3618 and in OLSD you will hit those everytime.

And you never have to worry about failed O2 sensors or a failed MAF.

I run my daily driver 2001 TA in OLSD, and it runs great, here some of my logs (see how WB AFR tracks commanded AFR)...

Cheers,
Joe

yes i have a lc1 wideband and i have been reading the tuturials. i just finished building my map for ve tuning and going to hit the streets here soon to get some data. one thing i dont understand though is on page 7 of the auto ve tuturial it says change pe multiplier to 14.63, is this because you dont want to go into pe mode while logging or am i confused or will this be changed back after you get a good ve tabel.

PE will be changed back after you have a good VE table.

Some people set the PE they want and do AutoVE like this...
this may work, but the transitions to/from PE won't be BEN'd accurately.

An alternate method is to set PE to 14.63 and set the righthand columns of B3605/B3647 to the PE AFR that you want, and ramp up to there from the flat part of the table (ramp, not step)... this way the AFR transistions will be curves (not steps) which the BEN's will be able to track.

thanks for the info joecar. im going to give this a try, it doesnt seem to bad.

i have figured out how the auto ve tuning works,pretty simple. i am now having problems with my wideband. it is a lc-1. my external analog votage stays at .1 volts. the logworks2 software shows that i am running around 14. range at idle but efi live show 7.6 minimum reading. if i rev the engine it will show a small analog voltage increase. i have the lm programmer set up to read .883 at 10 afr and 4.216 at 20afr. any help will appreciated.
