Multiply your actual injector size by .7 and use actual latency's provided with injectors.

If you want to make the transition easier you can use your old settings but I strongly recommend using PROPER latency values. Using maf based latency values tend to get changed to meet some fueling needs.

If you have ID 1000's on E85 and stock Fuel pressure.

Scalar = 640cc
Latency values should be exactly as ID recommends with the injector sheet.
Modded stockers would be somewhere around 550-600cc
All I remember about modded stockers is 1.06ms for 14v...

I did this calculation already when I switched to using E. So I will essentially use the same latency and scaler settings that I am using now. Just wanted to confirm this. Thanks.

Yup I tried running the actual size of the injector and using my speed density load comp to make up for the difference.

I was @ 4 g/rev (limit of fueling) @ 3200 rpms :|

^^ I was going lean (like low to mid 13's) in boost... and couldn't figure out it then logged load and saw I hit 4.0 g/rev @ 16psi... (target was 20)

So having the proper injector scalar can be very important.

How is it going, you getting close?

Yep. I'm just making sure I have all my ducks in a row before flashing. Right now I am calculating MAPa from my old logs to make sure my Speed Density Base Load Compentsation (MAP v. RPM) table is on point. I'm super excited about this and can't wait to try it out.

Did you ever figure out what was causing your idle to hover around 1000 rpms? Did you mess with the Idle Target tables?

Haven't figured it out - I don't even notice it anymore.

Yea only rarely does idle follow the table

I'm waiting on getting a USDM 6 speed neutral switch (this could be my problem) as the ecu thinks I'm in gear when in neutral and vice versa..

My clutch switch isn't working either..

We'll see

Default Your SD calculation map MAP/RPM

Just for a test, I put 1 in all of the load cells of your fuel to load spreadsheet and the results are different for every column. Is this correct? Shouldn't it be the same or am I missing something here?

You put 1 in where? left or right maps?

You can only modify the top maps.

Post it up on RR so I can see it

Haha I'm lame with XL - I posted up a new one with instructions.

I think I get it now. Let me know if my thinking is correct on this. So, my OLD log indicates 3.13 load at 3600 RPMS at 24 PSI. MAP calculates out to be 38.7. This is what I will plug in for my MAP and 3.13 load is what I will plug in as my load at 3600 rpms in the spreadsheet. And this load is what will give me my load percentage to use in the SD Load compensation map. Right?

Yes are you at sea level. Also also make damn sure you take intake air temp compensation into account otherwise you will be rich or lean at certain iats

Do you recommend flattening out the SDLC IAT table or leave that alone and take the comps into consideration?

what on earth leads you to believe simply changing the load reference to SD is going to "pull the extra power out of the engine that we know is there?"

Actually ken on my stage two test car sd. Allowed me to run .3 afr and 1.5 and in some places 2 more degrees of timing over maf based @ 15.5psi (limited by the stock bcs)... Its an 02 stage 2.........

Fwiw

I know it sounds a bit stupid. But tuning was done within an hour on each. Weather did not change tgvs were open on both tunes

umm, sorry, but something else was changed besides the load reference.

next you're going to say that utec makes more power than hydra, which makes less power than motec.

Never checked power. Nothing was changed at all. Tried sd with tgvs it didn't work drove home and opened them via motor remival and reinstallation. Road tuned on the maf (stock box and lc1) knock checked with det cans. Stopped put in my 02 base map for sd and went back out for another road tune. I could keep afrs within .1 of my target in boost vs .25 from high to low variance from target with mafm started leaning it out and made it to 11.7 (remember only 15.5psi) vs 11.4 with maf before knock. Almost 1.5* of timing at peak torque before knock on sd.

No dyno but it pulled a lot smoother. It is what it is.... I have logs on my computer

93 octane was used and obviously the same tank. Temps were around 60. Timing based on total timing and lc1 was not touched between tunes (less than an hour apart.) I'm not saying I made more power I'm saying ipw was much more consistent - less fluctuation.

That's all I'm saying

What is the difference between Base Timing A_ and Base Timing B_?

i will say it made more power, i was tuning my friends car, pretty much identical as mine, vf37 tgv delete, all the goodies. his whp on airboys went up 40, and torque is the same, he is now at 320 and 280, i also gained 20whp and 20wtq, it is also way smoother. base timing b is used when you ahve the but connector in

I guess with nothing connected it will use the A map. I just read that with the flash block connected, B will be used.

yep i always have mine in so it not such a big deal, but you can make like a safe map on 1 and not two, or possible like a dd and race map or something

i'm not sure what you're trying to convince me of. you have absolutely no basis to say "nothing was changed at all" -- you changed the entire ROM image when you reflashed.

do you know that all the per cylinder compensations are EXACTLY the same? fuel AND spark? do you know that the knock sensor sensitivity is EXACTLY the same?

sorry, but switching to SD load reference isn't going to magically make more power. you can contest it all you want, but that's the way it is, and every time i see someone say differently i will call bs. there are many compelling reasons to use SD load, but magic horsepower isn't one of them.
