This and your previous video on fuel tables is exactly the kind of info that I needed. I am no tuner but I need something to get it started rings seated and into the trailer. Thank you for taking the time to make it.

You’re very welcome. Planning to do more all the time

Really good video! Thank you.

Thanks for the video very helpful

Great video Good information on adjusting the table as well

Great videos! Very helpful for us that like to mess our own fuel maps and timing tables all up!🤣 thanks!

Thank you very much

Great video as always need to get the 8.8 diff and gear swap finished on my big blue Jeep I had you tune and see if we can get the lockup to work properly if not source a converter they will play nice with the big cam and tires I have.

Keep them coming

I feel like should pay you for this info. This video finally made me feel comfortable enough to play with timing on my LS2. I was nervous to go above 22 at WOT. I just said here goes and put 26 at WOT and followed your suggestions on the remaining. The motor no longer feels lazy. I did have to put the timing wall in my map as well for idle but it was there before. With AC on and coming to a stop it wants to stall. The "wall" works to stop it. Thank you !

Glad you liked it Time to put fresh plugs in and make a nice hard pull and kill the engine and take a look at those plugs Maybe I need to do a plug reading video next

@@Whiteaw57 Plug reading would absolutely be helpful. Tried to get this thing on a dyno but not many shops around here, and the ones that are here really don't want to mess with a bone stock LS2. Another video idea possibly Flex fuel sensor set up for pump E85?

Yes! Plug reading!!!!🙏🏻🤣

Nice

Very well presented. I have an angry Mopar 440. Trying to get it smoothed out for street /cruising . This is way over my head. I'm an old points and condenser guy.

The engine will want the same thing either way. I just find it’s much easier to achieve it with a table rather than weights and springs and vacuum hoses. 😅

@@greenshortsperformance472Agreed! I used to modify the innards of my Lucas dissy to get the maximum out of my modified engine. It was very much hit and miss and took a great deal of time and effort. These days I type a number into a table and “bingo” it’s done!

Great information. I have a interesting situation that the motor shuts off when I put the car into gear, but starts and idles pretty decent. Any related videos to assist.

I also had that stall when put into gear issue, the timing "wall" GSP mentions worked for me.

Thank you for sharing your knowledge and tuning experience. In your opinion, what would you typically like to see for timing on an early 351c using EFI and timing control for total timing? In my case the engine has original oem iron heads open chamber 2v with 9:6:1 compression?

I wouldn’t be surprised to see 35-36 on something like that but I’d start at 32 and read plugs

Long story short,i have an ls in a jeep and do alot of backroading in pennsylvania where i run into some pretty old gas ,my goal is for it to run good on 87 octane,curious what your thoughts are my timing table,its a stock 4.8 with a mild cam,18 at idle to 1400 then 25 in by 3250,to me this feels about right, not alot of info on 87 octane builds, everbody is after maximum hp, appreciate any input ...thanks

i would carry a bottle of octane boost...... had to do this with my dual sport, bike would run on anything but ran so much better on higher octane

Love your channel, question: 66 Corvette 570 HP wet sump crate motor LS7, FAST 102 intake and TB, AHP heads redone, mill .030 .040 MLS head gasket, CNC port. Terminator X, redoing the timing and fuel map, starting off from max 24 deg, down to 21 and checking data logs for knock, all good on acceleration but we now get an intermittent knock on startup, timing goes to 33 deg, 100% knock and retard table kicks in then back to idle 18 deg and runs fine, the knock is only 1 audible knock on first 1 second of cranking and start up run and that's it, no more knock. tried reducing cranking timing from 15 to 5 deg no change, tried richer target air fuel, no change, the trace goes down the middle pink area like you have and transitions up to idle, tried pulling timing out of the data log trace and no change, it seems the idle and timing goes high right at first fire up, starts quick and runs fine.......have you ran into this issue before? O, one more data point, we are at 5,000 ele, cranking PSI went from 170 to 208 after the head work, guessing we are around 12-1 now? Thanks in advance for any input!

Turn off the cranking fuel prime and let it get up some speed before it tries to light off. Ran into the same problem on my LS7

@@greenshortsperformance472 Thanks for the quick reply! when I first got my Terminator X your vid that shows the DBW throttle settings saved the day, It would not start without my foot on the peddle, your knowledge is impressive! thanks again!

Just wanted to give you some feedback on your suggestion on my fuel prime-crank knock, results....It works thanks again, no more start up knock! 2 more questions if you don't mind, you mentioned checking the timing old school with a pointer, have you seen many LS7s with the crank trigger off? in the process of rebuilding my 7 with AHP ported heads and BTR sg 4 V2 cam, vid up on my channel for entertainment. What value do you put in for air temp Vs timing? I have a little retard dialed in after 115 deg and retard up to 5 deg at 160 air temp. the C2 ls7 I'm working on has the air cleaner next to the radiator, not good but no room on a C2? Thanks for sharing all this cool tech!

Your timing adjustments are fine. They'll all be a bit different but its good you're thinking ahead on them. As far as checking static its never a bad idea. from GM they're usually very close. If you ever have the wheel off or you have an aftermarket crank id definitely check. I once had a machine shop install a wheel 92 degrees off. That took me a minute to figure out

27 degrees for a ls3 head is a lot isn't it? Beyond 22 degrees was only worth a couple hp on mine.

No it’s not. And I’ve seen that before as well. It will get flat in that region
