Anyone changed their tune?

[Rockettman]

I'm considering - sadly - to contacting Lidio, to get a 91 octane tune (as I have his 93 tune now); because of the gas prices. It's gonna cost me well over $100 to fill-er-up.

Have many of you gone back to a lower octane tune?

Is there really a big difference in street performance?

[Spectragod]

Are you N/A or S/C? I tuned mine to 93, but it's not a DD, I'd contact Lidio and get his opinion, email has always gotten me good results, he generally answers them in the evenings.

It's not a dailly driver; but when it is time to hit the pump...HOLY GOD! Hits the wallet deep!
Just don't want to be disappointed with a 91 tune.

[RacerX]

I do my own tuning. All it needs, if anything, is to be backed off a couple degrees. You could even try it yourself with your SCTXCAL. Try backing off 2 degrees globally and you should be all set. If you hear any pinging, subtract another degree or two. Or just call Lidio. He'll take care of ya! :beer:

How much is the price difference between 93 and 91 where you live. Here it's like $.10, so if I'm bone dry it's only an additional $2, not sure you'll experience the savings you hope, especially if it's not a daily driver

Petro Canada's 94 is about 4 cents more per litre that their 91, couple bucks per fill. I run SCT's 91 tune and i will get a ping here and there running 91 only. I alternate filling with 91 and 94 and she runs like a dream. I have thought about trying the 93 tune i have loaded but the previous very knowlegable owner said he didn't feel a difference, so i've left it alone.

If you do go down to the 91 tune i would be interested in your take on the differences.

93 Is getting harder to find around here. It's all going to 92. I was woundering if I needed to change, retune, or just stop at White Castle before every fill up.

[Mr. Man]

Lidio loaded both 91 and 93 in my tuner. Can't find 91 around where I live but I understand it's popular in the mid-west. Doubt you'll notice a big difference and the octane # at the pump is the minimum octane allowed. Depending on who mixes the formula at the refinery you may even get 92 or 93 and pay for 91.

Watched on YouTube jlt was dynoing and stated that 93 gave the car more hp

[ctrlraven]

From factory the car was tuned for 91 octane, since 93 octane is more readily available across the US that's what everyone uses instead.

I just fueled up with 15.2 gallons @ $62.00 USD.

Drive your foxbody more as I am sure it gets better gas mileage probably or at least should, that will offset the cost of fuel for the Marauder. lol

Octane by itself doesn't give more HP. Octane has ONLY to do with "Pre-Ignition" or "Ping" caused by higher compression engines. It will not contribute to either performance or economy, nor will it make the engine run any "smoother".
Higher octane fuels contain anti-knock compounds to reduce the temperature of the fuel as it burns.
Adding higher octane fuel than is actually required by the engine management system will only result in two things:
1) A thinner and lighter wallet
2) Occasional difficulty in starting on cool or cold days, and perhaps an inconsistent idle and low end drivability until it warms up.

I've made my own tune for the Petro-Canada (was Sunoco) 94 octane, which is just a bit too aggressive. In most driving, it performs admirably, but on a hot day with the engine hot and maybe some unusual gasoline, I get some ping on the 2-3 shift at WOT.
When I was running this tune, I would keep the tuner in the car just in case I had to fill up with 91 octane. That did happen a few times, and I had to detune to the 91 octane tune (by Zack).
I could always notice a difference, both after detuning, and again later after filling up on the 94 and retuning.

I now run 91 octane, because I have a costco card and a costco gas station nearby, so the difference between their 91 and the P-C 94 is about $0.10, which is about $6 per fill up. Not much, but it was winter so I was okay with it, and over the course of my 1-year membership, that should work out to a bit over $300. Meh. Maybe more because the car is a bit less fun to drive, so I granny it more.

So, if you want to save some $$, I'd have to side with Kramer - Not the gas, man!

P.S. I plan to work out the timing on the 2-3 wot shift, but if someone already has done this, I wouldn't mind a copy of the table mods/diffs ;)

[Ms. Denmark]

I've been driving my Aviator on 89 octane for a long time with no problem....but I do put 93 in the Marauder.

Haha - that's not a bad idea right there :)

I'm getting mine back on the road and tagging it Historic, will only be able to drive it on the weekends or to/from events but it's a 5-speed, full suspension upgrade (handles like a dream) and was getting mid 20s (miles per gallon) when I drove it before. I do a lot of running around with the girlfriend on the weekend and driving the foxbody will save me money/wear on the MM and keep the mileage down on my Taurus as I only have about 9k miles left on the warranty.

[Rockettman]

^^^ I can say that doing all my shocks last fall; getting rid of the 18 year old tires (I know, I know); and getting that alignment done (it's still not right!); driving my Fox is a great deal of fun again! Waiting for "put the top down" weather.
Of course, sitting on black leather in the hot sun summer; is kinda like sitting on the stove after cooking eggs! Still fun though.

[bugsyc]

:confused:I bought my xcal3 from Lidio...Now I want to change a shift point..1-2 at 6000rpm instead of 6200 where it shifts now....Because I didn't ask for user adjustability,because I didn't know I had to,I am unable to do this...Anyone else run into this? Anyone else with Lidio's 93 octane 3.55 rear,at what RPM does your car shift??Has anyone else run into this situation and have a solution??....bugsy.....:confu sed:

[Rockettman]

^^^ He won't sell his tunes with user adjustability. Some other's do...he doesn't.

[RacerX]

Lidio gave me three tunes on the xcal3 I ordered more than two years ago with all the user options enabled and I never asked for them. LLidio will be more than happy to help his cusomers out. :beer:

[Rockettman]

^^^ maybe because he didn't know me. That's what he told me on the phone when he emailed it to me.
For me, that was fine. I wasn't going to change it anyway.

[NonaDAbove]

...I have an appointment with Lidio's dyno in just over three weeks.

Since I got my Marquis street legal again, I've reduce the Marauder to weekend duties, when I can enjoy it and not just do a three mile run at 25 MPH back and forth to the office.

I've put nothing but Sunoco 93 in the Marauder (with one exception when I bought 91 instead) and I swear by it. When Ultra 94 was available, I used to put it in the Grand Marquis, it was like catnip. I think the modulars know the difference.;)

[mrjones]

I've been thinking about trying to get him to adjust my tune. I like the tune, but the torque converter doesn't lock up till its in OD and at 63mph. Since I've got the tune I've moved from the country to the city, and I spend most of the time well below the speed where it will lock up. I'm sure I'd pick up a few around town mpgs as well.

I'm just going by what jlt said after they dynoed the car. If I could find link I'd post it. There words not mind.
