Sweet Johnny, Ill give it a shot, havent touched the smt7 for a few weeks now

 

Thanks guys. Looks like I need a good scan tool. I have heard various recommendations, but what should I get? I just want something good enough to tune properly. I do not have a Palm or similar (FYI). I do have a laptop though.

Please let me know what you guys think I should get and where. I remember hearing something about a “BR-3” (?) but that may be old news at this point.

 

If you have time sometime, lets get together and you can check mine out. Honestly its liek a wideband, unless you are going to be doing multiple vehicles or constantly tuning your car, its not worth it to spend a good amount for something youll not use that much. Trust me, i spend money alot like that....lol

 

Buy the OBDII BR-3 Scan Tool from URD (or obddiagnostics.com). It works with your laptop.

Doug -

Should I just snag what Brian suggested in the post above, or should I wait and check out your set-up? (I think you and I used your set-up a while back when I first got the SMT 6). It was cool.

Let me know what you think. Thanks.

 

Its your call, you really just need the scan tool for your initial global config, and after that youll need a wideband to properly tune the matrix. I would recommend that you put the money you would for a scan tool towards a wide band(cause youll need it any way) and use my scan tool that is free. My 02 cents

 

Alright that sounds good; what wideband should I get? I know Brian asked this question recently I think but I really don't feel like searching right now.

 

ummm, Christian... Something to keep in mind is that a wideband isn't going to do you any good outside of Open Loop. Sure it'll show you the A/FR, but you can't affect it.

From where you are in the process right now, I think that spending $83 on a BR-3 (order direct from Bev and save some cash) is a much better investment than $350 on an LM-1 (plus the bung install).

Being able to see the Short/Long fuel trims and to validate timing is most helpful.


Re: the negative numbers... You mention the INJECTION map, is that really the one that you're trying to use? No dude, use the FUEL map (analog map 1). The injection map is for control of an external injector - like a 7th. There wouldn't be any need to take fuel out of it, 'cause you'd only be having it on when you need MORE fuel than the stock injectors can deliver.

 

I was looking at the LC-1

As it will wire into the smt and the smt will display the correct fuel/air ratio even at wot. Permenent solution.

I was also looking at a portable non-perment solutions like the LM-1 so that I can tune my truck as well as others vehicles.

 

Ummm... The LM-1 still requires a wideband sensor to be installed. If the truck is already running a wideband, then you could certainly hack the cable to parallel the meter into it, but it's not setup to just plug & play that way.

I have an LM-1, and have a second bung on my Y pipe to fit the wideband when I need it.

 

I agree with you Mark, but eventually Im sure you would agree that it would be best for Christian switch over to a MAP sensor to trigger the open loop mode. That way he could change the 14.7 Air/fuel ratio that causes the mid range ping.

As far as choosing a scan tool or wideband, its up to you and how much you want to spend. Ideally to get the best tune you need both, and since I have a scan tool that Christian can use, thats why I suggested the wideband

 

Buy a wideband AND a BR-3 like me and then you can tune it all! Are you going to plan on getting an oxygen sensor signal conditioner?

By the way, in terms of wideband O2, I have the Innovate Standalone kit (LC-1 and XD-16), the display is programmable, the analog outputs are programmable, and it can be used with a data logger later if you feel really hard core (the LM-1 does logging too, BTW). I was originally going to get the PLX-M250 w/ gauge, but Brian at URD gave me a free upgrade since I ended up picking up the whole kit from him and he didn't have it in stock (and I spent like $1700 total).

After having seen what Innovate makes in terms of data acquisition hardware and quality of products, I would go with them over PLX.

 

Most LM-1 setups thats Ive seen come with the additional sensor.

From the reasearch Ive done, I concluded that you can not hack into the existing factory wideband because it runs off of proprietary specs that can not be interpreted by third party software.

If I remember correclty, I think Christian already has a free bung from the EGR was removed.

 

Mastacox, you are absolutely right about having both, but why buy a scan tool when your buddy already has one and will let you use it?

 

$1700?! Yikes!

The first thing I will do is get together with Doug since he is local and see how much we can accomplish with his BR-3 and go from there. Surprisingly, my 4R runs pretty darn good as it stands right now, it just keeps throwing that code which is annoying. I am also almost positive I am not getting the power I could out of this thing right now. But is still goes pretty good.

By the way Doug, I found an abandoned road out by me that would be GREAT for test and tuning.

 

Well, that was the Fuel Upgrade kit, 2.2" pulley, Wideband kit, OBD-II Scantool, SS Exhaust bungs, USB cable... :pat:

It was worth it though, with all of the advanced equipment I feel like my 4Runner is a space ship now

 

Right, but I was reacting to you saying that the LM-1 is "portable non-permanent".


'k... but I think that's up on the header, right? It's on the left side header on my Downeys.


Sure, at some point, or an ESC1 (when they work right). But I'm trying to save him some cash outlay. He doesn't _need_ the LM-1 now, and having a BR3 will always be useful.

Or, like he just said... don't spend anything and see what your reader can tell him now.


Christian... Don't miss my point up above about the INJECTOR versus FUEL map on the SMT-6!

 

Oh don't worry, I saw that! (I am still shaking my head) I can't believe I did that.

 

hahah thank god i forgot about that hah!
