Experimenting with Octane Adjust Ratio (LOR) settings in SCT

[8nutz8]

I'm hooked on corn.... 14.5 psi with 25 degrees of advance... knock sensor still wants to add more....no KR anywhere...

Can't get good logs right now, traction is a problem... too cold.

Boost is nice but boost with a ton of spark feels incredible.

I had so much spark, I couldn't get to my boost target cause it didn't need it to hit demanded torque. The solution was to up the power.

I'm tired of jumping threads to respond to you... lol...

Yea, you were at 27 degrees of spark? Brad seems to think I should be good where I am at since I'm just shy of MBT for my current load... but said depending on my fuel pressure he might want to add more... dunno... like I said... tires cant get warm enough to get a good 0-100 log...

My spark limit is at 27 and I'm hitting 26.75 peak. Once summer fuel arrives I suspect we will ride the limit. I'm also not opposed to blending up a bit if necessary. Or dumping a couple of bottles of HEET in the tank.

Better life through chemistry....

I can pretty much duplicate both those situations. Got to the spark limit of my E20 tune and wanted to see what was left with a higher blend since FRP was still solid. Got the same verdict from Brad saying i was approaching MBT. There is a ceiling for everything and you reach a point of diminishing returns. Not to mention i've learned that spark can be a very powerful . . . but potentially dangerous thing. And if i was a payed tuner i wouldn't shy  away from the idea of backing off of MBT a bit, commanding a little more boost and ultimately making more low end torque instead of being a peak HP queen.
That being said, i still might be curious to make the man give me a 100octane/E20 tune come track season.

Yup, he told me he set my spark limit to 25, and the bit of logging I am able to do right now shows I am maxing out my spark.. brad wants more logs, just haven't had time to or good weather to do it.

In Ford, Brad, and my knock sensors I trust...I log constantly and even when I'm not I'm always watching the X4. I understand the risks involved and there is inherent risk seeing how far the platform can be pushed.

On the wild end of the spectrum we've got BPD showing us what can be done while spending your kids inheritance. On the mild end you've got me exploring what can be had with nothing but a tune, 3 bar, and a little corn. I've saved enough in fuel cost running E to pay for my mods. Both methods provide valuable data for other owners to decide what direction they'd like to go and what performance level can be expected.

Horsepower isn't real, all I care about is my torque and how far I can carry it. Max torque is 500 RPM or a downshift away anywhere I ask for it. Peak HP queen isn't even close to accurate.

Still using ACES, FoMo?

Once a month for preventive maintenance.

I'm nearing 20K so almost time to have MrsFoMoCoSHO get my valves inspected.

i completely agree with the above statement and i'm taking a similar approach to yours. i wasn't calling anybody specifically a hp queen but rather advocating for a torque under the curve tune instead of peak hp tune that a lot of aftermarket companies like to tout.

I just jumped on the e30 train... I like it... gas mileage has went down a good bit though. I looked yesterday, it said 12.5mpg..

I hear that... good thing mine stays in the garage most of the time.. I need to send Brad some logs with the latest E20 tune but weather is not great.

I was debating on meth or nitrous but I might just wait for the new HPFP and run more E.... not sure how high I want to turn it up though.... it's pretty beastly right now... 14.5psi holding with 25+ work of spark..and I'm not even tickling KR... just wants to keep adding...

That happens when you beat the hell out of her,...

Jesus that's worse than my straight E85 tune, lol

I'm around 19 with a 50-50 mix of city/hwy. If I drive her nicely I can get close to 21 but I can't tolerate that for long.

Just curious, is you OAR scaled higher?

That is a question for ajpturbo... I don't know. I really haven't been pounding on the car other than for logs... kids are always with me. They love riding in the sho
