Default Dale's Part of the Week Discussion

Hey Everyone!!

We are starting a “Part of the Week” thread on the forum to get some good discussion going on different parts that we always get questions about. I’m sure a lot of people have the same questions and maybe just don’t ask so why not get it up here for everyone to see and learn from. I am open to any suggestions for parts that you’d like to be discussed in this thread so feel free to PM me directly, jstbstn. I’ll post up a new part each week with some details about it and then questions and discussion can go from there.

Please help to keep this thread on topic

First Part will be posted soon!!!!!

Default Part 1: Cobb Accessport

This Week’s Part of the Week:
Cobb Accessport

Why: Because it is one of the most common parts I always get questions about.

http://www.cobbtuning.com/Subaru-Acc...ap-sub-003.htm

When Cobb released the Accessport a new era of simplicity in the world of off the shelf tuning began. They brought to market an interactive and easy to use device with great dealer support from Cobb directly when needed. Cobb has always continued to release new updates to not only the hardware but also the maps available and back end programs as well. Things changed yet again when Cobb released Accesstuner Race software that any Accessport owner could download and use to custom tune their own maps as well as having integration abilities with aftermarket wideband oxygen sensors.

In the shop I find people always have questions about their Accessport’s and how to use various functions so let’s kick off this thread with some questions about the accessport!!

Ill start. As someone who does not own one, Ive had this question for a while, are the Cobb Ap's vehicle specific? Ie, does one need to buy and STI specific AP versus a WRX AP versus a 2.5NA AP?
Maybe this is a noob question but Ive got the impression that it is the case but not too sure.

Question: Cobb says the dealer can't tell that you flashed your ecu under a warranty condition. But everyone else says they can. There's never really been any solid answer about this... still wondering.

I can field this one.

COBB flashes back a "stock" ROM back to your ECU, but any dealer who knows what they're doing will know how many times it's been flashed irregardless of AP, OS, EcuTek etc. They're not really going to check unless you went in complaining about your engine blowing up or something.

Yes, depending on your year/model, there are a few different APs out there.

AP-SUB-002 is for 07 STi for example
AP-SUB-003 is for 08+ STi

Check cobb's site for compatibility.

I happen to have a rare discontinued Cobb AP for my 08 Si (8th Civic), which is different as well.

I used to use the Cobb AP when my car was relatively stock. Ran their stage 1 ots map without any problems. However once I got a downpipe and ran the stage 2 ots map the DAM was stuck at 0.8, never got full timing, and the engine was knocking quite a bit. Did anyone else have the same results? Was using 94 octane.

Some more info on the accessport,

It also offers speed density now, and a hybrid mode which switches between your MAF during idle, and MAP when cruising or WOT.

You mean IAM (ignition advance multiplier)?

GR/GV's or any 32-bit ECU should optimally be at 1.0 IAM. Ideally (after flashing), you should be able to run the car around for 5 min, go into boost a few times, and then it should have learned 1.0 IAM by then.

If your car was pulling timing, and was knocking hard it could be

- bad gas (our 94 apparently is no where near as nice as US 91/92 AKI), for that matter interior gas is really crappy too.
- wrong map (08's IIRC have smaller injectors from factory, maybe this has something to do with it?)
- bad flow/exhaust leak, do you also have a cat-back? or downpipe mated to stock exhaust?
- other mods causing issues? (BOV? Piping of any sort?)
- a whole host of other problems (health of car, etc etc)

I have found through several first-hand sources that COBBs OTS maps really like COBB goods. I believe their stage 2 calls for their intake/dp/exhaust as well. However, they should work decently on any STi with DP/Exhaust/Intake. Also was it knocking during idle/cruising/WOT conditions?

I've read a bit about the bad gas in the thread on RS and that seems to be a possible source. The only mod to the exhaust was the downpipe. Stock exhaust and stock intake. Knocking was during normal acceleration in the city/cruising. Was scared to go WOT with the DAM only at 0.8 (I'm going by the Dynamic Advance Multiplier). I've switched since then to a custom map from Eric and no problems. After a minute of driving it went to 1.0 immediately and no knocks at WOT.

Ah, it would seem that a map tailored to your car works. It's kind of the reason I'm not a big fan of OTS maps. They do work for what they're intended audience is, but I'm still thinking it must be some 08' thing they never factored in.

Glad to see it's resolved tough.

One thing to always bare in mind too with OTS maps is they are based on gas available in the US which is greater quality it would seem than what we get. HPA locally ran tests between chevron 94 local gas and chevron 92 from Washington and with nothing other than fuel being changed they were picking up a gain of 8-12% wheel horsepower. From personal experience I believe our 94 isn't good enough to be able to run a OTS 94 map without having knock issues no matter what year wrx/STi you have and in some vehicles even the 91 maps are a bit blah. From my own tuning, I've found that this is mostly due to the timing maps needing some TLC to get them inline. The fuel maps are beyond pig rich and the boost maps are moderate. Altering these maps based on DAM and Fine Knock Correction to keep DAM high and FKC low to non-existent has yielded great results in my own vehicle's. Obviously, getting the fuel map to be more appropriately fueled in all load zones instead of pegging rich by 1psi and altering boost maps certainly yields it's own benefits in drivability and fun as well.

My only beef with Cobb is they do not support JDM ej207 ECU.

They make great products that is not in dispute.

They say they do not have the demand. I hope things may change as more JDM engines are available.

Default Part 2 - Wideband AFR gauge

I've had a few people asking for quotes for widebands lately and a couple members sent in a suggestion that they would like it to be a topic of discussion. Since we have been talking about engine management, it flows quite nicely into use of a wideband when self tuning. Personally, I've been tuning via wideband installed in the downpipe post turbo for years with great success. I like having a gauge type that I can see at all times to be able to monitor my vehicle without having to be datalogging. I recently purchased an AEM UEGO wideband which will be getting installed this Monday hopefully into a SMY gauge cluster bezel.

So! Who's using these? How are they being used? Who has questions?

Let's keep this discussion going!

I have a Innovation LC-1 which supports both 1V/5V as well as serial output. That way I can setup a gauge as well as connect it to my laptop for logging.

I installed the AEM wideband yesterday and my initial impressions of it is a very reactive gauge and visually appealing. It uses a high quality Bosch O2 sensor with locking connector. The back of the gauge uses two plugs, one for the O2 sensor and one for the wiring harness to keep install nice and clean. You get more than ample cable length to install the gauge so when running in off the downpipe behind the turbo I only used about half the length and tucked the rest away up under the dash. The only downfall with the gauge is the output 1V/5V wires are completely bare and no connectors are supplied whatsoever which is obviously why AEM offers this gauge for such a great price. It would be simple enough to wire a serial connector to it but then a serial to USB will be required as well so it's a bit of a pain if you are itching to data log with it. At this point, I'm comfortable editing maps just having it in front of me at all times so I'm not going to worry about that for the moment. All in all, it's a great gauge for the budget minded to keep tabs on how you're fueling especially if you are tuning your own maps!

On top of that, the SMY gauge cluster is a thing of beauty and very OEM in design... Super Happy with it!!!

Kind of late to the party but I have had my innovate MTX-L in for 5 months now. I replaced the sensor last week as it was giving random full lean signals on a whim (mid pull... that was scary...). I have a feeling a free air calibration would solve my problem but the sensors are fairly cheap and it is an equal amount of work to do either. I may just stuff in the old sensor once I'm don't tuning just to save it.

But overall I think I prefer it over the AEM. The MTX-L is slightly cheaper than the AEM, still has all the functionality of the LC-1 including serial connectivity if you don't have an input for it in your engine management. It also looks very similar to the AEM with the sweep.

Another nice feature of innovate gauges is when a sensor does fail, it typically tells you. I've heard quite a few people complain about having to replace their sensors on a regular basis (3-6 months) with daily driving while using the innovate gauges because it kicks out error signals while AEM sensors (exactly the same sensor) lasts for way longer. It is not that the AEM lasts longer, it just doesn't tell you when it wears out. It will just read incorrectly.
