Default Going open source, saftey periperals?

I am going open source today with the purchase of a tactrix cable.

Few questions:

1. Is it a necessity to have a wide band 02/other peripherals?

2. How much power am I losing by not having an uppipe (I have a intake/downpipe)?

can't wait to tune . . .

If you're going to be doing any meaningful tuning at least get a wideband sensor and a knocklite.

The uppipe is worth a few HP but the big advantage of a catless uppie is better turbo spool.

Not to mention a cated up-pipe has taken out a few turbos once it's kicked the bucket...

What is the cheapest wideband available? they seem fairly expensive.

I thought that the up pipe was a big part of a stage 2 tune? It is encouraging to hear it is mostly spool.

and you don't have to worry about the cat breaking up and jumping into the turbine. I recomend the Innovate LC-1. I got mine for $200.

I think one of the cheapest would be the AEM UEGO gauge. It's a good wideband gauge. The LC-1 is a nice unit but you have to buy the gauge separately.

I recommend the LC-1. It's pretty cheap, good unit, feature rich. You can log it with Ecuedit (pay version) or Enguinity. The basic gauge is only $60 and is good enough as an idiot light. For actual tuning you need to have the log threaded anyway.

I second what Freon said. I use the LC-1 for all the tuning that I do and it works great with Enginuity as a logger.

Is the knock light necessary? From what i have read the open source tuning seems relatively safe. That being said if it is necessary, I want it, as a ruined engine is the last thing i need.

Someone should sell a Open Source kit will all the basic hardware. . .

If HP per dollar is my goal. And I need, a tactrix cable, knock sensor, wideband sensor, egt?, etc. How much are we now talking. Should I just get a cobb accessport, this may end up being cheaper (and safer).

Several sites (including Innovate directly) sell a LC-1 + Tactrix cable combo. I don't think you really need anything else. EGT might be good if you really want to push it, but you can live without. I don't use a knock light. I don't think it is required. Can't hurt, I suppose, but I'd still count more on careful logging.

I do, however, have my stock knock sensor hook up to my car stereo. That only takes $5 in parts from Radioshack.

there really is no comparison. they both will provide a good base map without tuning at all. If you have a stage 2 car, there are plenty of good open source stage 2 maps out there that you can burn onto the ecu and forget about it.

if you want to jump into tuning, you will need this equipment either route you take.

Can i do an open source tune with a trusted stage 2 map, safely, with out a wide band o2?

I have a DP/intake, but no up pipe/cat back. . . yet.

I don't think you need a knock light. Follow this link for an Open Source kit:

In the past, if you entered enginuity as the discount code there, you'd get a 5% discount.

Thanks for the link. I want to do that up pipe, just looks sounds like such a bi*$#. Need to find a stock one to gut, prior to install.

Thanks for everyones help, Stage 2 is going to be fun.

I'll have one for sale cheap soon! (just have to get some ambition to box it up...)

anyway, yes you safely can run a stage 2 map from osecuroms without tuning on it. and although it is morally and legally questionable, you can also get your hands on a cobb stage 2 map fairly easily if you want to try that.

So, do you load the cobb map via open source? Feel free to PM. Thanks, interested in this concept.

its an interesting concept, yes. But its stealing! i have very high respect for cobb, they are one of the pioneer's in subaru tuning! I think stealing their maps is very wrong.. If you are going to go open ecu, use open ecu maps, dont take a map from cobb.

Fair enough, I can appreciate that. i dont see why they would be better anyways.

cobb maps = extremely safe, the power output it not at its highest point due to the safety measures.

xpt maps = noticeable amounts of extra power, but need to be datalogged to make sure you are not causing your motor any harm. I've flashed a few people that i had to modify the map slightly to make it run right.
