I have been tuning the MAF and VVE the "old school" way since 2017 on my cammed L9H Denali 1/2 ton.

The E38 ecu is so good at processing data (compared to my old 0411 in my swapped RX-7) that I...

deleted...fat fingered post, sorry.

Yeah, like I said in my original post, an earlier EOIT worked.

I have a bad habit of doing adjustments very extensively and once they work I seem to brain dump the memory after about a year. I am...

Sorry for not getting back sooner.

Went out last week and attempted an EOIT of 5.71 & 5.89. Both numbers required more fuel, brought back some minor low rpm bucking and fuel smell was worse.

I...

So after looking at some more cam event calculators with my specific camshaft specs I am going to try an EOIT of 5.89 and 6.0

That ends fuel spray at 331.5 & 340 degrees of crankshaft revolution....

If you look at my attached EOIT excel spreadsheet you will see that I chose to run a setting of 5.29 over the oem setting of 5.55 due to the fact that my cam starts its Intake Valve Open at 277...

anyone who is willing to help answer an odd question: https://forum.hptuners.com/showthread.php?91003-EOIT-on-a-TSP-228R-Is-my-thinking-right

I need a little clarification:

I know you all recommend that a camshaft that has 0 degrees of overlap doesn't need EOIT adjusted but the 228R is a pretty aggressive cam with zero overlap. Both...

Plx sm-afr. Great unit and has great heater control for the LSU 4.9 sensor unlike innovative (unless they have finally figured out a better way to modulate it).

I will keep this thread posted on that matter. I usually pull my plugs after hard WOT tuning and every 300 miles city driving.

I input an EOIT of 5.29 tonight (calculator NEW NORMAL for IVO) and that was the #! Exhaust smell gone and idle up to 1800 rpm was richer on the wide band.

I uploaded my OL SD tune and dialed in...

I have a 228R cam, 114 lsa, zero advance. The EOIT calculator states that my NEW normal for EVC is 5.67 and IVO is 5.29. TRUE normal is 6.17 for both (since IVO amd EVC at 356)

Tried 6.17, 5.87,...

Here are the differences. My tune VS Frost's (compare tune.)

93913

93914

93915

93916

Not to stir the pot but why is the data conflicting between WS6Firbirds's and Frost's?

Back in 2013 when I did my head swap and fell victim to purchasing some imitation Bosch 42lbr's I purchased...

Found the issue. Wideband 02 need a recalibration in free air.

It is always the simple crap that gets ya.

LS1 FC3S RX7, tuned myself, been dialed in perfect since 2015. I run OL MAF/SD hybrid. LS1, 228R 114lsa, AI 241 heads.

Car always at idle runs 14.6:1 +/- 2% AFR error. Tuned to 12.5:1 at WOT.

Man this is killing me......I had to reinstall 2.24 and now I have lost all my user defined formulas for my wideband and associated PIDs.I knew I should have saved it somewhere else on the computer!...

Yes you definitely need to put a load on it & get some good gas in it. Will help immensely and you should be on your way by the sound of it. You already got the basics down so it won't be too hard. ...

I just recently purchased a 2008 1500 Sierra with the LH6 5.3 and without skipping a beat burned 2 credits & got into it with hptuners. Right away I was able to see the drastic difference between my...

I just replaced my LS6 manifold and ported OEM 75mm TB with a TPiS LS6 intake(my same manifold I sent in to them) and Holley 90mm TB. This is the first start up datalog and it ran really well.

I...

You ever figure out why it was using the low octane table?
I too am encountering this problem when I am in closed loop with MAF and VE operating.

This ever get figured out?

I too am having the same exact issue. In OL Maf and OL SD my high timing table is used BUT when I go into Closed Loop with MAF and VE combined the pcm uses the low...

Yep. Thanks to everyone who helped. Very appreciative!

Got it fixed today.
It took lowering MIN FUEL MG to .028
Lowering Min In Pulse & default pulse to .927 from 2400rpm to 1200 rpm
Short pulse adder was left alone.

Those adjustments brought decel...

Thanks. I should have used a better word other then hesitant...more along the lines of "last resort" to change min mg. I will try it tonight.
