Hi all. I am considering switching from APv1 to RomRaider for my tuning needs.

Can I use my Stage 2 93oct OTS map as a base image in RomRaider? It is my base map as long as the AP is married to the car. Basically I want to get the image from the car onto my laptop, unmarry the AP, re-flash my ECU via RomRaider and Tactrix cable, then datalog and tweak.

I do not want to start from stock map due to the fact that my car barely runs on the stock map now. I have TurboXS FMIC, K&N typhoon intake, Maddad headers/up-pipe, Invidia catless downpipe, and HKS Hi-Power exhaust.

Thanks in advance for any helpful input. Yes I do know how difficult/dangerous tuning with opensource is. I still want to do this as long as I don't have to start from a stock SOA map.

Yes you can use the OTS map as a base image to start from, so long as there is no realtime map applied on top of your base map. FYI the OTS stage II map doesn't have a whole lot altered in terms of fuel and timing maps, and you will most likely want to rescale all the maps to a higher load point (don't know how much boost you want to run) before making any alterations---after you pull the stage II rom that is. Most of the changes are in boost and wgdc tables and CEL disables.




I really don't know what kind of feedback you want or what your question is. What do you mean by he car barely runs on the stock map now? It seems like you're good to go if you want to start going with open source.

Thanks for your reply. My only real question was can I use the OTS map as a base image.

By sayig the car barely runs on a stock map, is that it is extremely sluggish until ~4500rpm. It loves to stall, and dies randomly at idle. I have had no issues with my stage 2 OTS, but I know there is a ton of room for improvement over this.
Thanks, James

Just purchase a XPT Stage 2 map from Braden and use that as your base map. Zen Cart!, The Art of E-commerce

Thanks for the info Shamoo. If the cobb stage 2 that I already have will do the trick I think that is what I will use though. That extra $130 for XPT's map is almost a wideband...... I will save that link though for future reference.

Anyone else have useful input?

You *could* log vital things like timing, knock correction, wgdc, boost etc on your current Cobb map, and maybe apply those settings to a custom maps of sorts That might provide a nice starting point.

Thanks Tgui, I had considered that.

My basic though process was:
1)Make an image of my base map (cobb stg2)
2)Unmarry AP
3)Reflash the image via RomRaider
4)Datalog, Datalog, Datalog
5)Tweak
6)Rinse and repeat as necessary

The stock map is actually a good place to start. I would advise against ripping your OTS Cobb map, and using it with anything else. In fact, I dont even know if it's (easily) possible.

Thanks again everyone for your input. I've decided to purchase the cable and play around with some maps. I need to read a TON more info before I actually start changing things. I will keep everyone updated on how its going though.

On a side note, I've saw a lot about launch control using the rev-limiter fuel cut. Does anyone know if it's possible to use an ignition cut with open-source? Seems safer than cutting fuel.....

It will work if there's no real time map applied over it. It's in the romraider FAQ. I did mine when I received my tactrix cable just to fool around.
The standard OTS maps don't have any special coding in basemap form when you pull the ROM.

If he has basemap/realtime map, then yeah it'll be hard because the real time map overwrites the ignition and fueling and he won't be able to pull the realtime stuff.

Besides, pulling the rom won't hurt anything. It's when he goes to reflash that we need to tell him "uhhh I didn't say I knew for sure" hahaha jk





But I agree with you that he should start from scratch, even if he does pull his Stage II rom. It's the best way to learn. But I also think it would be good for him to compare his stock ROM image to a Stage II image to look at changes.

i would like to know about the launch control question as well...im waiting for my cable to get here!

[reid-o]

I think it's best to post that question to the romraider forum.
I have no interest in the launch control, and so I never really tried to look it up, but I do recall seeing threads there about it.

Actually--this is just FYI--a lot of Street Tuner users use Enginuity to make advanced changes to their ROMS that regular street tuner cannot do. So they're using both Street Tuner and enginuity. But they have to flash their basemaps with the AP first. Pull it with enginuity so that actual rom from the AP is edited--to keep the marriage between AP and ECU--and then edit and flash back. And yes, a lot of us often wonder why we paid for Street Tuner in the first place after toying with enginuity (actually the real time tuning is valuable).



Plus reflashing with enginuity is ten times faster than the stupid version 1 AP.
One of these days I'm going to kill my ECU flashing my basemaps with that thing.

Omg, realtime tuning would make some things soo much faster to tune.

nobody knows the limit, there are people with hundreds of flashes on the stock ECU and it hasnt given up the ghost yet. Somebody has a spare ECU just in case though.
