I had a tester, will order a new one tomorrow and maybe ship in a 55 gallon of the E98

Check out the Syvecs S8 as well its plug and play and combined with a fuel flex unit auto switches into Meth or Ethanol maps, can be all controlled with a Toucan unit to access diff boost/traction maps. Google Syvecs S8 but im getting a virus hit off the sites at the moment.

So I arranged a meeting early this morning with a 458 S and a local's 12C, of course the NY Hamptons weather did not oblige and I was left by myself (well with my dog) in the rain on the corner of a quiet private estate road. I am interested to see in the real world with this higher power and better spooling if I can keep with one of the global guru cars of today. I can pull a 458S above 60 mph but have not been able to catch a Macca yet.

I also checked a brief datalog I did the other day in the wet.

Using the E85 with MAFLESS seems to have had the added benfit of shifting my torque curve more to the right. I am now getting 210% torque at 5200 rpms or so which keeps my crank torque at 600-630 lbs-ft at those rpms above 4400-5400. Before, under the 93 octane MAF set up my torque peak was at 4300 rpm or so and a good 100 less by the time I got to 5400 rpm

that 2.8sec 60-100 is a lot of torque! sound like you have a good max out k24 setup before building you engine and go bigger...
i bet you can kik that 458 *** but close race
if you can do more good logs and share it

Yeah, I think we are at max for K24s, absolute max.

When it is dry this week I will do a long 4th gear pull 60-130 to 7k rpms and see

Take into consideration that going Mafless means those values of LOAD are calculated and not actual.... but nevertheless the result is fantastic and E85 is really good fuel

Yes implied loads but the vbox verify seems to confirm the calculated power and torque (by reverse engineering) roughly at those values.

Just had a dog ate my home work result as I pulled a 6.5x on vbox and no effing verify... oh well, temps low at 55F this morning, 4th gear is a beast now and I can do quicker 60-130 mph just 4th rather than 3rd-4th

I did get a messy pull as 3rd slipped tires and shifted 4th early

100-125 mph in 4th 2.64s

Why do you shift so early? I saw under 100mph shift...that should be a lot less than 7000 rpms. I think you should be a bit quicker shifting later

I usually shift near 95 mph or about 6300-6500 rpms in 3rd which was optimal............ the pull above had the tires ripping and roaring in 3rd and I had left PSM on which was lighting up like a pinball machine... I will do a dedicated 3rd-4th and 4th only 50-150 mph this week and see what times we can verify. It was quite cold when I did that particular run and my tires are a bit of a problem.

One thing is for sure, Eurodyne with Tim tuning and some E85 gets results that are much better than I could have ever hoped for

Andrew if you get grip soon ,try 2nd gear to 4th directly with a 7100 rpm limit, i think no one has done this before...

The nice thing about both of those EMS is that you could get sensors and tune in a Traction Control strategy that'll keep the car going in the direction you want
