Re: Bin for Trickflow and high compression
Pretty much what the guys have said here... just need to start at the beginning. Change the basics... displacement and injector flow rate, and then make some light runs to start seeing where you're at with BLMs and work from there.
I'd invest in a WB O2 sensor though (if you haven't already), no two ways about it. Otherwise you'll have no idea where you're at for Open Loop and Power Enrichment... which can actually be dangerous under hard throttle.
What cam are you running BTW?
Also, 11:1 CR? What fuel are you running?

Re: Bin for Trickflow and high compression
11:1 compression on a 383 running on 93 octane? And that cam in a 383 is going to be building some serious dynamic compression.
hmmmm.... really curious to see how that works out.

Re: Bin for Trickflow and high compression
This is how Lingenfelter built them. It’s been in the car for 21years so I would say it’s worked out fine. Just trying to perfect the tune with EBL flash.

Re: Bin for Trickflow and high compression
Eh i would just set wot max load kpa to 34 by 3600 or so rpm depending on how you want it to come in and what intake/cam but thats a good start. Then taper up in timing as kpa drops more to vacuum. Like 34 at 90-100 kpa 36-38 at 70-80kpa. 38-40 by 60 kpa and under
If a good sized cam somewhere around 25-28 deg at idle rpm, ramp in mid 30’s off idle. So your 40-60 kpa 1200-2000 rpm areas are like 35-38 deg
that will build a base map

Re: Bin for Trickflow and high compression
I noticed a significant difference between the LT4 and LT1 maps.
A long time ago I generated some plots comparing the maps between various masks... the file is actually downloadable from my website...
http://ultm8z.com/Spark%20Table%20Comparisons.xls
Any rate, if you go to the tab for LT4 vs 94 Transam, you can see how the LT4 has a significant amount additional timing over the LT1...

Re: Bin for Trickflow and high compression
Are those numbers just the main table alone or does it take in account the other timing adders/subtracters?
a lot of the lt1 files from fbodies i see have a 5 deg adder thats applied in wot that ppl tend to miss lol makes that 33-34 actually 38-39

Re: Bin for Trickflow and high compression
Which heads are you running? I have a ported superram and the way I degreed my cam I'm running well into the 8s for dynamic compression. Im also running an EBL Flash.
I run my timing at 36*. Trickflow should have given you a card with the heads that said they like total timing in the neighborhood or 36-38* if Super 23. I tried 38 before but that resulted in the knock sensor having a coronary.
This is with 93 octane and .035" quench.

Re: Bin for Trickflow and high compression
Then my max SA is around 30. I’ve been fighting false knock so trying to be real conservative. Getting some exhaust leaks welded up this weekend. The roller rockers are also pretty noisy in these setups.
