My max at almost stock (only BHR coils) was 208.58 @ 8727rpm on a hot day in June running the "stock style" map with the AccessPORT. I'll post up the log in a bit.

 

I will be working on the nitrous tonight and afterwords I will do some logs and third gear pulls.

 

Shouldnt there be a guideline to how you want us to post our datalogs... like from 0-70 or 3rd gear pulls from 4000RPM etc. Where do you want us to start from etc. or is it up to the user???

 

Yeah we should standardize things and list if you have scaled your MAF or not. I say 3rd gear at 50MPH pulls.

 

^^^ Scaled your MAF, explain what that means, im not familar with that terminology... And 3rd Gear pulls from 50mph works for me...

 

oh man, you don't want me explaining it, i am still trying to wrap my head around all this. Read the help file on Kanes site and the thread in the engine tuning sub forum. That will give you a better understanding

 

OOOh ... I'll be posting some soon ... awesome thread! We need more like this

 

I guess "scaled" isn't quite the best word to use. Calibrated is more in line with what is going on.

Since you have the ability to alter the calibration of your MAF, you change the amount of airflow the MAF registers under certain conditions. It's possible that you could change the calibration of your MAF at top end which would produce a larger or smaller number than actual.

So trying to compare two different RX8's airflow numbers and try to make sense of the power output isn't feasible because there's no constant between the cars.

Basically, don't get hung up on the numbers too much as each car is different.

 

Try this guys, let me know if it works.

Lol Righhtttt.... Well I guess mine will go with unscaled... Im gonna leave soon and ill log some data for yall...

 

Dang, well I logged some data and it seems im reaching a max of 243 g/s for my MAF, may be just a spike... Idk how yall are getting around 200, must be my AEM CAI??? Idk but at WOT from 8-9K rpms I see a steady 200+ g/s reading on my MAF from my datalogs, I seem to be getting a average of 215-225 around those rpms as well...... Ill attach them shortly...

EDIT: Apprently my file is invalid, any ideas at how to make this work?

 

looking for the auto maps for the cobb, bought one that was unmarried and it was on a 6spd, i checked cobb site but all the maps are for 6spds

 

Works fine but a graph would be nice too

 

Running hawt .... wat was the temp outside?

How did you get your titles to stay and not scroll?

 

That's a buttload of air ... I doubt real healthy N/A rx8's go over 210g/s ... we need to get MM in here

 

I will work on a graph, any particular RPM range?


The outside temp for that log was close to 100F, it's mid 90's or so now. South Texas

 

Lol if I can find a way to post it I will... But I do get an average of 215-228 from 8-9K rpms no lie...

Here we go, lets try this...

We do have almost the same type of mods and tune, we also pull almost the same g/s.

I think my guideline at page 1 is valid.

 

These datalogs are from 6 speed manual, yes?

 

Expect a noticeable increase in g/sec from datalogs in the middle of the summer versus in the middle of the winter.

 

okay so what do you we want to see, what data? here is some data that I copied from this morning. I will post the full log later.

Okay guys, uploaded the Data to google docs.

FYI, I have a 6 speed manual, slightly modfied Cobb Stage 1 map (no maf scaling changes just fans, revs, etc), BHR ignition, BHR fuel pump, BHR midpipe, HKS catback, stock intake with WIX filter and custom cold air duct.

Does anyone have any experience graphing this stuff? I played around with it but some of the values are so low it does not visualize well on a graph.

 

Here is a 2 axis plot

Let me know if this is what you're looking for.
