Mine is a 350cu in, AFR 195 heads, thanks Jim, Lingenfelter 74211 cam , 52 TB, hooker headers.

Does anyone have a tune for a similar set up that they would share? I have my tune real close using Tuner Pro but would like to see what some are using for timing etc. especially around idle. Mine idles pretty good just want to see a comparison.

Thanks!

cshuman

Would someone please tell me what there timing is set at around idle that has a set up close to mine?

cumbercr

I use 18-20 degrees at idle.

cshuman

Thanks for the response!

I'm just getting into this data logging. I'm going to have a lot of questions probably for you 2 guys among others.

My car don't idle for sheite!

MrWillys

Auto, or manual with what injectors?

Your 383 with a "smallish" cam should idle great without a lot of tuning.

cshuman

Sure will
Thanks!

I compared your bin to my current bin and the timing at idle is a degree or two lower than mine. I also noticed that your timing table is about 10% higher in the upper rpm's than mine. Did you adjust your timing to that level thru tuning? Do you have a similiar setup as mine? Just wandering because I want to try the lower idle timing but also may try the higher timing as well.

MrWillys

PE spark modifier was zero'd out and all timing was put in the main tables.

Edit: Did you look at the closed TPS table for spark timing at idle?

cshuman

"Enrich Power Spark vs RPM" table we are both at 0, is that the spark modifier table you are talking about?


"Spark Advance Closed Throttle Vs RPM" table?

On my bin it is set around 26 degrees and on yours it is set around 22 degrees at 800 RPM's

MrWillys

Whatever you see in that table you need to add initial timing to, so if you have 26 + 6 = 32, mine is 22.1 + 6 = 28.1, and stock is 20 + 6 = 26. Your cam does not need that much timing at idle. Honestly, I took the time to create that file for you. Had you bought from me it's what I would have sent you. Why don't you try it and see if it runs better?

cshuman

Try this table or the whole bin?

MrWillys

Run the .bin, and modify the VE tables to suite your vehicle. They should be close to start with as I've tuned numerous vehicles similar to yours.

cshuman

I'll play with the two. I've already adjusted the VE tables on mine but am interested in your timing tables.
Thanks for the input!
