needs a bin to get me going I have a 1995 corvette with 383 stroker flat top forged pistons 11.4 to 11.5 compression ratio. Cam is custom 226/234 duration @.50 525/525 life on 1.5rr stock 3.07 gear 4l60 2200 stall no o2 sensor or maf it’s on a SD tune with stock motor and the cam I played with for awhile but new set up is way different need some help thanks. Idk if anyone still even dose tunes on these cars anymore lol

Hi
There's a couple of us on here. Checkout Steveo's EEHack pages. That's pretty much all you'll need.

'95 Z28 M6 -Just the odd mod.
'80 350 A3 C3 Corvette - recent addition.
max ve table is 7000 can I edit xdf and add 7500 so I can pull to 7200 rpms
My question is why delete the MAF and 02s? Get a LS3/LS7 cartridge style and a matching 4" spectre housing. Then get a matching 4" lamnier screen. Install in a 4" air intake. Then put the 02 sensors back on. I have run a 232/244 @ 0.050 cam on a 108 LSA with 02 sensors without issue.
Cause the headers did not have o2 bungs and no one around me could weld then I have always tuned my cars in the past by reading plugs but I am getting o2 bung flanges that’s why I was asking for help on a starter tune. I don’t no anything about maf tuning or o2 sensor tuning. I am old school tune by feel listen and plugs
you ain't no older school than me and many others. Step into the 90's and learn how to tune. Sheesh. Listen to Fast and I'll post a MAF table for a 4" tube and cartridge, Or just use a stock 453 gram maf from a 2001 truck, if you can manage to max that one, then convert to cartridge. I doubt your 383 will max that maf. Sorry for bluntness.

lol your good man just learning the tuner pro it’s pretty awesome program and the eehack I read my plugs regardless lol they can tell you a lot
Shoot, I'm jealous of you guys that have a Lt1 and use steveo's stuff, it looks like it rocks. When I started tuning in the 90's we worked in hex, there was no software. You truly couldn't charge enough. Good luck on your project and yep, reading plugs is an art all by itself. Luckily I've been crackin at this since I was ~12 :)

Some of the tools here were highly advanced compared to the "Hex Method."

I picked up where someone else left off on the old 299 ECMs $99 code in my old TBI powered G20. I used a partial hack and used a motorola dissasembler and compiler back in the day.Originally Posted by 1project2many
Need some help I got green giant 42ib/hr injectors from corvette mods and was wondering if y’all no anyone with some offset data so I can get them tuned better I currently have setting from Ford lighting green tops but having trouble starting up when motor is warmed up. Thanks

if you need help reproducing the data in cells that make sense in EE try this tool: http://drr.ikcest.org/app/s2852
i never really bother tuning the offsets below 9v i just leave the table flat there (since the engine will run like a bag of crap at that low voltage anyway)
Ok cool that’s what I have but wasn’t sure if I put in the offset correct when I save it it automatically puts in a number on the voltage offset. The offset adder I but - numbers and it goes straight to zero
