It's the alcohol multiplier table. That's what multiplies against the density. Quick and easy thing to do is to put the same one in that the SD side uses. Won't be right but its a heck of a lot...

Pop the rails and injectors out and see if ones leaking. I've had them brand new out of the box get stuck open. If injectors check out and you know the part number on them matches what they're...

I would highly advise going back to gas and verifying your fueling to be 100% there, but until you update that density multiplier for the 30% extra requirement of ethanol, it's going to stay super...

You should be able to use the DD tool now and once you're nearly done to do the final corrections to the DD table. It actually works really nicely and Michael did some great work making it.

Hmmm, I've fixed several doing it that way, as all of the multipliers on the gen V's seem to work by lower numbers add more fuel. They're almost always lean if you leave the stock setting in there....

Yeah, people don't realize how important these background tables are :) You should have some more zip now too ;)

Your not going to see any changes, but this should change your idle where it's most likely intermittently struggling to idle due to leaning out.

Post a log from a cold start with a 3 min idle, then drive, then hot idle. Hopefully that's short enough to post. Idles need to be with AC and heat off and in park. Most of the time what I see is...

Yes sir. Franklin NC. However, I don't have a dyno or anything like that. Alvin is in Mooresville NC too if you need or want a dyno. I'm not sure if his is eddy equipped, but he does have a dyno.

That setting is actually used to switch to advanced algo's or in laymens terms, a more rapid oscillation that will also add and remove more fuel for the oscillations. Basically a switch for colder O2...

Then put the lt4 pump and injector data in it. That should get it going.

I may not be following entirely correctly here, but you should use the lt4 injector data as a whole, so all of the profiles, offsets and voltage tables (should be 2) and not just the flow number. The...

Pulley and CAI are the only two mods on the ls9. I don't go any lower than about 50 to 55 psi with factory injectors and then make high pressure about 5 psi above that this way it blends better and...

I'm tuning an ls9 in Europe right now doing this same thing. I really started looking out for it since Sgod's original posting on it. Only reason I bring it up is because the only mods to his are a...

I only get what I would call halfway expensive on the newer gen V's, so anything using an E90 or newer ecu. I only get that way because the background coding starts getting pretty expensive for me...

Yes

Your spark table looked like one from a truck. Didn't realize it was a car. Either way that should work better with that flex table. Everything looked good. If you really want to dial it in you'll...

They may have done the boosted truck I looked at too then. A lot was screwed up the same.

This is the SD alcohol multiplier - put it back to stock

146676

Take that same stock SD alcohol...

Try them both and see which it likes. Just make sue the rest of the cal is right first.

Just a couple of notes after looking at it - actually looks like another one I recently looked at for...

Figure out what's up with cylinder 7 - probably a cracked plug or loose wire then adjust your O2 settings.

I find it varies depending on the cam or build. Most of the time the NA ones actually like richer on ethanol whereas boosted likes about .5 leaner. I think that just has to do with how the ethanol...

Ok, that makes more sense

So the bad fluctuation is basically the valve bouncing and pressure dropping and spiking over and over again to try and keep up with the loss post valve to hpfp demand. Cool... I know all of my...

So the bouncing pressure isn't a glitch exactly per say. Its a flow problem. Think I said that a while back on a couple, but good to know it could be either and has been confirmed by someone else.

Swaptime makes the best harnesses. Mitch has gone to putting the correct connectors for the different years along with including things such as supply pressure sensors, fpcm's if wanted, the correct...
