Questions on Tuning with Tunerpro RT and Ostrich

[puhrot]

So I am pretty new to the tuning game. My current setup is a 92 eagle talon AWD.

PTE 50 trim external gate setup
PTE 680cc injectors
Walbro 255 high pressure pump on stock wiring
Buschur Racing AFPR
"street core"FMIC
3" exhuast
2g Mas

I orginally had a maf-t and afc-II for tuning. I was having nothing but problems with that setup. On the dyno we had to take out 5 degrees on base timing and not run over 18psi without serious knock issues. I left making 290whp on a dynojet which left me pretty dissapointed for a 50trim setup. So I ordered up the Ostrich emulator and Tunerpro RT to replace the AFC-II and Maf-T hacks! I have read up what I can from this thread http://www.labattz.com/phpBB2/viewtopic.php?t=11843&highlight=tunerpro which has a ton of info on the Tunerpro Ostrich combo.

My main question is what would be recommended for a basic safe setup to get the car going. I do not have a wideband so I will not be pushing this on the street tuning. I just want to get a good setup going and then bring it to the dyno to see what I can get out of it.

From what I understand so far I was going to download the bin he has configured already for the 2g mas. Then go into Tunerpro and change the values for my inectors and fuel pressure accourdling. With this get me a good safe tune? Or could it possibly still be way off as far as AF and Timing tables go? Also is there any disadvantage to running the extended fuel and timing maps? I see them being nothing but good but I know people do not run them. Any reasons why? The reason why I was wanting to run the exteneded maps is I think that was the issues with the high knock I was getting last time we tuned. It seemed to be over running the ECU and trying to run very high timing while under boost. Which is the reason we had to pull out the base timing.

I do Have a Laptop and I will be using it to run the Tunerpro RT and I also have the TMO datalogger which I will be using.

So I guess to summarize what I am looking to do is get the car running right now so I can run around town for a couple weeks working out the bugs. This way I can save time and ultimatley money spent trouble shooting on the dyno.

Burning you own chip is the only way to go in my opinion. Unless you drop the money for full standalone.

With TunerPro and modifying the bin, it completely blows the current release of dsmlink out of the water.

If you set your injector size correctly, then you will want to modify the fuel maps at the least, as they are very rich normally.

I thought the fuel and timing maps the extended code came with sucked. I redid them completely.

Well running rich until I get on the dyno doesn't matter to much to me as long as the motor does not go BOOM! But as far as actually modifying the fuel tables there is no way to do this other than enter a value into each cell one at a time? I thought I remember seeing someone with a AEM doing the WOT and low settting then doing a blend type of deal? Maybe I am dreaming or is this just one of the many reasons why this is free and AEM costs a crap load of money?

I dont know how aem works, but with tunerpro you just modify the cells you need to.
You simply enter your target A/F ratio, if your injector size is set correctly it will run very close to what you tell it to.

There arent really that many cells to modify, especially the cells you hit at WOT. There are only going to be like 7-8 cells.

I like to use a shorter method to adjust where I am on the fuel/timing maps. This way I don't need to make several individual changes to the fuel and timing maps. I adjust the maf scalar at address D49A (549A). Changing this number will adjust the load reference point. Using a higher scalar puts you farther down on the fuel and timing maps when you go WOT. A lower scalar keeps you up higher on the maps where the timing is higher and A/F is leaner. It's a quick way to retune for pump/race gas, too. FYI the stock maf scalar value is 5E 86 for a 1G. 2G cars use a value of 7A 03. In my car with a hacked 2Gmaf I'm using 90 E3, though I've had it up to 98 83 before.

I try to have mine run so that its reporting to correct amount of air flow. I just have a seperate chip done for race fuel. It took a whole 5 minutes maybe to lean out the A/F values in the upper part of the map and add more timing.

I can drive around on the race map all the time if I dont get into high boost, because all the lower values (below 3.0 grams/rev and below 4000rpm) are the same in both maps.

I definatley like the idea of running the ECU at the correct air flow. That is my whole point to switch over to this setup. If you start messing with the scalar wont this make staying in the stock load ranges more of a pain?

 

[crazykid]

Wow, so how many people are currently using this type of setup? I would like to hear more from people using this. Ive been dead set on getting DSMLINK but this looks to be just as good if not better than dsmlink for a whole lot cheaper.

 

[LeeRichmond]

is anyone running this with a 2g? Im going to do some reading but would like to know who in a 2g with eprom has done this and how they liked it.

 

[Ravenous]

There are a lot of people running this type of setup and milking every ounce of capability out of the stock ecu. If you want to get in on the action and see what it is all about check out the dsm-ecu group on yahoogroups.com. These guys know their stuff, there is even somebody on there running speed-density off the stock ecu. Definately worth checking out. However be forewarned that this is not nearly as user friendly as dsmlink... However the capabilities are constantly increasing and it is much cheaper.

I haven't read of anyone using these techniques with a 2G, I've searched around a bit. If you can, I'll jump on that right away. But from my research (though not comprehensive), it seemed like a 1G-only solution.
