So I've finally had a chance to read through the entire thread and have a bunch of SD convert cars ready to go but, I have a few questions:

1. How do I setup EvoScan's Map Tracer so that I can get Map and RPM on the X and Y axis and than input the Load/Map (VE) info from MAF logs? I haven't played much with Map Tracer and can't seem to figure out how to set it up to do this. I imagine I could simply reference the .csv file in Excel instead of using Map Tracer as I do know but, it seems much easier to obtain this info using Map Tracer.
2. Another EvoScan question I have is why when I load a .csv file does the load stop at 100?? I assume its a scaling issue but, again I'm not sure where to look to change this.
3. For the SD Map Sensor VE And Cal table - to obtain the load information that needs to be inputted I simply log boost and transvert it into kpa (by going into EvoScan's data settings and change the jdm map formula to 1.334*x and then change the psig to KPa). From this I simply take the logged 2-byte load and input those numbers with the appropiate kpa row?
4. For SD RPM VE I'm not quite sure what needs to be logged for this. Obviously RPM but, where is the percent calculated for the appropriate RPM? From an earlier post it appears that MAP VE * RPM VE = Load - if that is true and I know MAP VE and at what Load would I simply divide MAP VE by that specific Load to get a percent and reference at what RPM at MAP VE and Load came from and input that into the RPM VE table?

mrfred - to patch the latest v7t6 ROM with your SD patch for 96530706 I simply need to move the SD .xml info into the 96530706.xml file or the 96530006.xml file?

 

Finally I can give back a little bit to the SD discussion.

Jcsbanks has a post about this on the bottom of page 9 I believe, the discussion continues from there. Basically you'll need to change Map to load and load to loadold. I actually didn't do it this way and I think my way takes a bit more time but you end up at the same place. I simply mapped map on the maptracer then guesstimated load vs map (since evoscan doesn't use a centered table) then logged it and checked if my numbers came out about the same, where they were low I upped them a bit and where they were high I lowered them a bit. Once I was satisfied I started looking at STFT and dialing that in until I was very close across the board. Lean means load goes up and rich means load needs to go down. Then I looked down the columns to see where things were going and if it was rich or lean at the edges (RPMwise) I adjusted the RPM VE table. If I had to do it again I would pay more attention to the procedure provided by jcsbanks, mine took me a few days of to work and back driving.

Your load stops at 100 because you haven't loaded a rom. Open up maptracer and click on the lower grid and it will open a dialogue to open a rom, open the one you are using (or a similar one) and it will pull the scaling and the fuel table from that rom.

Yes, you simply log Kpa but I wouldn't necessarily make it linear, if you do you have to retune the car completely. If you tune to make load match airflow like it did before then you're going to have a better time unless the engine is so beefy that you end up with wonky and silly airflow measures that go in excess of what the stock maf can do, then you enforce your own rationality on it and the only thing that you care about is getting a somewhat linear scale with enough granularity to get the car to the end of the track, at that point you would want to go linear.

I just used STFT to figure this out, it took about 15 minutes after the rest of the tune was heading toward decent.


I'm not sure if 96530706 inherits from 96530006 but if it does then you can place it either place, if it doesn't then yeah just add it to v7. There isn't a change to the actual rom deep down like a Tephra patch so all you need to do is have the xml and move all the values in your new tables.

I hope that answered everything.

 

Yeah I do recall reading the above but, where does the relabeling of Load to Loadold and relabeling MAP to Load get done? I presume in the data settings within EvoScan? The reasoning behind relabeling than I assume is so that MapTracer grabs the MAP data (which have been changed to Load to trick MapTracer) instead of the Load data.

How is VE determined in the .csv log files? I assume, given VE=Load/MAP we need to make a new entry for Load/MAP in EvoScan using the data from MAF-logged Load (2-byte?) and MAP? If so what formula is used to obtain this data?

I feel like a dummy now about MapTracer, it was pretty easy to figure it out after you mentioned adding a .hex file. My problem is is that I'm running EvoScan through a Virtual Machine on a MAC and there is no right click button One thing I did find is I got an error message when trying to load my 96530706 ROM into MapTracer. The error reads - "Object reference not set to an instance of an object" Not sure what that is about. My other ROMS load fine.


Thanks mork for your input.

 

9530706 doesn't work because of the way that the xml is handled, evoscan doesn't think it is a working rom and doesn't know where to find the addresses for it. There is a thread about maptracer on one of the first 5 or so pages on here that I think was started by fostyou which has a workaround as well as basic instructions for working maptracer. It seems like many people miss the part about adding a rom.


I thought that the relabeling was done in the log itself and that the RPM VE calculation was just done with a few pieces of data by hand.

 

For those of you who have converted to SD; what are you using for an intake/filter setup? I'm having trouble sourcing an Evo specific 4" pipe, the filter is the easy part to find after that.

 

I edited the csv log file in Excel by relabelling and calculating the VE column, when finished make sure to save it as csv again.

 

Dejon Tool has plenty of options on their website (dejonpowerhouse.com). I bought intake pipes from them for my DSM in the past.

Actually, I just got done emailing them. They are going to make a special order for me...a full 4" no-mas pipe with a crank breather hose and DV recirc adapter. They can pretty much make whatever you want, if you don't see your particular combo on their website.

I'm just about to switch to SD, so I will be using this 4" pipe, and Amsoil air filter (as big as will fit, once I measure when the pipe arrives) and then I will fab a cold air shield with a sheet of HDPE.

It's funny, after I posted I remembered Dejon Tool and took a look at their site. You think that would be my first idea since I'm currently running their 3" intake . Anyways, I ordered up their mafless 4" pipe. Let the SD madness begin

I'm also looking at the Amsoil 4090 filter, depending on available space. I'm currently running their 6065 and like the quality.

 

I just ordered the 4" pipe myself, but I got it in aluminum with the recirc fitting and valve cover breather as well. I also ordered a 4" to 2.5" reducer coupler from siliconeintakes.com, since I'm on the stock turbo for now. I'll get a 4" to 3.25" for the FP Red once I decide to upgrade.

 

I received my Dejon 4" intake pipe today. Definitely a nice piece.

I made some rough measurements and (since I am an 05 wth ACD), I onlt have about 6" past the end of the pipe to the ACD reservoir.

I'm thinking I'm still going to get the Amsoil 4090 though, since it's the only 4" flanged filter that I see with an inverted/open cone end. If need be, I can push the filter 3" onto the pipe or even cut the pipe back.

It's definitely going to be fun trying to fit this all together, along with my Synapse DV (it's huge) and then trying to fab up some kind of heat shield. But, I think it will be well worth it in the end when done.

 

Finally converted the car over to SD; haven't had a chance to do much tuning or logging but so far everything seems good.

Can you tell which setup was the restriction???:



Free'd up some space and simplied the engine bay:

 

nice - thats what I was going to do with mine

 

Very nice. My 4" Dejon pipe is sitting right here. The Amsoil 4090 should be here this weekend. Is that a 4090 that you have there?

Let us know how you like the no recirc. I chose to include the recirc fitting on my pipe. I didn't like that loss of boost between shifts on my DSM when I ran VTA.

 

That looks fantastic, but something tells me I'd have difficulty fitting something similar around the ACD reservoir.

 

I'll tell you soon enough.
