Stage 3 settings results
I have good news and bad news about setting the fuel settings to Stage 3 as suggested by some. The A/F ratio went to an idea 12.5:1. Horsepower took a serious 17 pony drop. This probably explains why my fuel mileage went up. I was getting 37 mpg at a steady 70 vs. 33.5 before. Also my ignition setting was set to 91 (what we call premium in CA).
I'm trying to decide on next steps. My shoot from the hip thought is to put the ECU settings back to stock and run lean until someone has a better solution.

linh,
i think BlackC230Coupe was speaking of what would the results be of running 93 octane fuel with the stage 3 settings, not swithcing the settings to 93octane.

Do some of you people only get info from this forum but not give info to this forum? I know that there are at least three people that have this fuel stages setting before Buell but don't say jack about the result !!! It seem to me that Buell and i are the only people that give real result (good and bad) in this forum !!! Are you guys afraid of the manufacturer when it come to say negative things. Come-on, this is a forum for discussion, that meant we discuss good and bad info.

that is half of your gain. that doesn't sound good. are you going to try upsolute?

Buellwinkle:
Have you try the any of the Octane Booster along with your Stage 3 setting? I have been using Octane 104 Black bottle with a Volvo V40 (running @ 14.7PSI vs stock 6PSI). Those Octane booster can give you as much as 7 point increse in the Octane rating.

btw, has anyone has the ECU set to Stage 2 dynoed the car?

I may try to get cooler spark plugs to deal with the hotter cylinder head temps. Linh picked up about 12hp with the cooler plugs alone.

The 91 Octane adaptive is retarding the timing too much across the entire band. Let the ECU do it when it senses ping instead of running that way all the time. I know my MB Tech and Kleemann both recommended Fuel Quantity Stage II and to leave the Ignition adaptive at base. As I suspect the 91 Octane setting is what is causing your performance loss and has little effect on the A/F ratio. The Stage III Fuel setting appears to be balancing your A/F ratio, which is good to know.
I should note, that I left the ignition adaptive at base because 93+ Octane is readily available here in my area and I did not what to retard my timing and take a performance hit. I set the Fuel quantity to Stage II as recommended to enrich the mixture now that the pulley is installed. IMHO I believe that is the best combination of max performance without running to lean.

I've read on other forums that the octane number on the menu is the european rating. We've been though this before without a final answer but from the posts it seems that base is the best setting for the timing. A setting of 91 on the euro scale is like 87 here so that would account for the power loss. Try going back to it and see what the net result is. Remember, the timing also will make you engine run much hotter if it is not set right so that is where the excess heat is from.

Linh, Are you talking about colder plugs in a 02 C230K or an older SLK? I thought colder plugs weren’t available, and probably not needed as the original plugs were cold enough, for the newer 2002 C230K Coupes.

if i was to get the ASP pully and had my fuel setting changed to stage 3 and my ignition setting to 93 octane. since that all i ever put in my car, would i have a loss like buell did? or will it not make me loose to much HP? comapred to the ASP pully at the stock settings?

if i understand correctly, what buell did was comparing the setup with ASP pulley with stock settings to the setup with ASP pulley with Stage 3 and 91 octane. he gained 17 hp less at the wheel using the later setup. so what he implies is that ASP pulley with stock setting would give u more gain.
if u use ASP pulley plus Stage 3 plus 93 octane then u're pretty much the same to his setup.

Bear in mind that before changing the ECU settings I did not experience detonation and it was not pulling back timing. This was a precautionary measure. Also keep in mind that it only runs moderately lean during full throttle accelleration which is not something you do for long periods at a time anyway. So while a cooler plug may increase HP and reduced the possibility of detonation at full throttle, it may impead performance and fuel mileage the rest of the time so it's a trade off although it may appear good on a dyno which is run at full throttle. More testing would have to be done to determine what configuration is optimal.
Testing Linh did with the Upsolute chip did not increase a/f ratio. This problem applies to all 2.3L motors (newer SLK230 and C230 coupes) with any pulley kit. On older SLK230 and C230 sedans, the issue is resolved with a fuel presure regulator.

Also agree. Unless getting 91+ Octane is an issue in your area stick with the base ignition setting, and set the fuel quantity to Stage II or III depending on how much time you spend at full throttle.

The ignition settings are Euro octane according to an expert I talked to yesterday, as such 93 is really about 89 US octane! Stock setting is optimal according to him and seeing the cars he works on, he knows.
