Just a quick update guys. As you guys know Renntech is coming to town. We are inviting SL 550/600 to join us on the dyno day and try the Renntech software. If you are not satisfied, we will flash the car back to stock and you dont have to pay a single cent!

amgme

interesting! how much if we're satisfied? you got a long stretch of road w/ no cops in your area so we can do some quick gtech 0-60 runs before and after? i know it's not the same as a track but given the circumstances, it's better than nothing right?

AdamG@NorCal

Cushing parkway. Special pricing of course. Retail is $1995, but on that day, its special pricing.

amgme

Is the pricing 1700 as you stated a week ago or is it more special than that? i'm hoping for the more special.

AdamG@NorCal

Its less if you do not want the dyno runs. Its about 1600 with dyno runs!

PS: The dyno location is charging us $100 for 3 pulls (1 run, and we need pre/post runs) with A/F ratio. We are dyno tuning after we get a baseline.

amgme

so about 1500 w/o dyno runs. is there really a need to fine tune a stock sl550? don't they have a program that just works w/ all stock sl550's since it's pretty much the same components in a stock car. yes?

what day is this happening?

AdamG@NorCal

November 5th and November 6th. We have couple of cars lined up on both days. Yes, we do have the files worked out but we would like to custom map for each of our clients cars; maybe on different octane?

amgme

i might be interested. do you have any sl550's lined up on the 5th? i don't want to be a guinea pig.

AdamG@NorCal

I have one possible SL 550 and S550. But plenty of 55s though.

amgme

cool. let me know if the sl550 makes it. if it has good results, sign me up for the 6th! please post b4 and after dynos. a 0-60 gtech run would be appreciated too, if possible.

AdamG@NorCal

Might need to borrow your Gtech buddy! LOL!

amgme

Hey, if you need to borrow it, it's cool w/ me as along as it's used to test it out.

AdamG@NorCal

Yes, feel free to come by on the 5th and try it out.

AMG 17GT

Good idea i want to see this.

AdamG@NorCal

amgme, please come on the Nov 4th instead. We'll be at the shop and we would flash your car first so that you can see the difference. Bring the gtech pro.

amgme

adam,

i'll probably show up and see if there's a difference. what time?

AdamG@NorCal

10 am - 4 pm.

AMG 17GT

Any updates, i am real curious how this turns out.................

mercedave

as a new owner (04 sl 500) can someone explain in simple terms what this is all about? I assume new softwear would increase horsepower but how and can it be done on a 500?

AMG 17GT

Check out prior 500 threads on a search.......... this is for 550 and i just realized its a saturday dyno......... cmon Adam show us the numbers baby

AMG 17GT

Well what happened this weekend? Amgme? Adam? ......Do we have dyno numbers on the new chip?

amgme

romeo, adam will be posting the dyno soon. the chip picked up about 23hp and 22 or so tq. the trottle response also improved. adam gave me the chance to drive home on saturday with the upgrade and make a couple of runs and see how i liked it. i did about 3 gtech runs and got about 0-60 in 5.1s. i didn't get good traction as the ground was a bit damp. i should also mention my car had only 700 miles on the od.

sunday the dyno was done and they flashed it back to the original program to do a base line. my stock dyno number was pretty low. if i remember correctly, i only made 289 rwhp. WTF? how does that translate to 382hp at the crank? with the chip, i got 312 rwhp.

i'd like to thank adam and his crew and renntech for everything. they are first class. i ended up purchasing the upgrade.

so to summarize, yes, the renntech chip does indeed give you more hp and tq in addition to improved trottle response. if you happen to live in a state that has 93 octance, your gains might be more. i definitely think baseline numbers will also be higher than mine w/ 93 octane.

i'll be happy to answer any questions.

AdamG@NorCal

You are welcome. I hope you are having tons of fun with your car now!

AMG 17GT

hmm....very interesting........i wish u had dyno before u went in there.........can u be more specific about throttle response..............i feel you made the choice to buy chip because you just wanted to get stock hp.......something wrong here................on a positive note we had a fun time in atl this weekend............my best time was 13.573 at 101.....car felt a little weak top end
