View Full Version : Tactrix flashing and Mapping?

Hello all! I have had my 2012 Ralliart since august (2012). I have become to accustomed to its power and am craving more! :D. The only thing I want to do for now is to be able to Log/record my Stock RA before I do any tuning so I can compare it to after the tune. I am planning on using the GST basemaps in the future. I am currently Stock with the exception of a AEM Boost gauge and a metal Evo BOV & drop in purolator air filter.

Now for my question: If I buy the Tactrix cable and Evo scan, Ecu flash, Can I just log without tuning? I guess what I want is to do is to be able to log this without tune so if somthing looks funny I can take it to the dealer before my warrenty is shot down by a flash. Does this work?:confused: I would appreciate all/any help from you tuning gods!

Thanks!

you can't log the stock tune as is, unless you modify the map to enable mode 23 logging. This means you can access the data coming out of it to monitor rpm, knock, boost, etc. If you plug into a stock car without logging enabled it's just gibberish and no info.

So, I guess you can log it, it just isn't exactly plug in and go. Before you tune, click "read from ECU" and save the stock map in a zillion places, preferably in an email or something so it will never get deleted or lost. This way you can re flash it if you need to be back to stock.

Can someone chime in with the steps of how to enable logging on the stock map?

Yep you have to enable Mode 23 on your ROM and of course make sure you have the correct definition for your ROM.

Richard helped me with this ages ago. All I found was the stock tune was really crap and knocked all the time. Went back to the GST maps and it was all good.

OK, does anyone or has anyone ever "tuned" their RA using GST then re-flashed it back to stock to have warranty work done?

I guess I am just hesitant to do this if it will for sure void my warranty. I know Cobb says that their product "theoretically" is undetectable:rolleyes: but I don't know how much I believe that. Plus the GST seems to be better for what I want to do with my car.

Yup, tuned with GST, transmission broke (unrelated to GST.. pre existing problems), flashed to stock, got transmission replaced under warranty. but of course, you must accept any and all risk.

Yea I know it will be a risk either way but I am glad to hear from your first hand experience that someone has at least had success doing this! Your input means a lot to me thank you :D. That means that I will need to start increasing my knowledge of this process and possibly move forward with it.

Ok now maybe a stupid question do I need a A/f Ratio Gauge to safely do a GST Base Map? All I have right now is a Boost gauge...

No problem... Yeah the tune is awesome. Transmission feels better... pull feels better... way better than stock. Though there definitely are risks, do a forum search by my user name and you'll see my bad experiences. Though, I'm sure my experience is isolated and I don't want to scare you... but just be aware of the possibilities.

Good luck!

Ok so next week I'm going to order the Tactrix cable with the extension cable. One thing I have not found the answer for is what are the benifits/downfall of the 91 octane map vs the 93? I'm assuming that the 93 is better. Is this true? As of now a I run in my baby is 93 octane

I can only get 91 and pay 93 pricing. Grow some hair on your balls. ;>

For us up here in Canada, all you guys down south have it easy when it comes to gas prices ;)

yea, hey? its $1.04 a litre for reg..i think thats 89 octane. You do the $ and volume conversion..I was working up north ( that means by Alaska..not north of Washington..) and gas prices were $1.60 for reg..so when I came home premium ( 91 octane ) was 1.20..lets say I did premium and was very excited about saving money!

Totally off topic...

if u can afford higher octane go for it i say. since ur already putting 93, you might aswell flash that map to make use of it

Ok thanks for the input. Does anyone know though if there are any benifits of the 93 over 91 set ups?

Yup.. the main benefits are more BANG. One can argue it's cleaner as well. To the engine, not he environment. ;>

more power and burns cleaner.

You should be able to run a little more timing advance on 93 and hence make more power.

91 oct map vs 93. 1 degree of timing advance above 100 load (ie. on boost). Under 100 load (ie. when running under manifold vacuum, such as light throttle or cruising) there is zero difference. As far as I can see, there is no difference in boost or fuel settings, the only difference between 91 and 93 oct maps are to ignition timing.

To be honest, I run the equivalent of 91 octane fuel on 93 maps (AUDM/EDM GST basemaps only have 98oct). I've logged and logged; and summised that there are greater performance differences between brands of fuel (when it comes to propensity to knock) than there are between 95 and 98 octane (the equivalent of US 91 vs 93).

While it is strongly adviseable to run the highest octane available to you, I wouldn't worry too much about unintentionally mixing/using the wrong octane with whatever programmed basemap you have on your ECU. There are a ton of safeties, by the map tuner/writers, as well as built-in to the ECU to prevent physical harm to your engine. Worse case scenario you lose power (due to knock sensor feedback, ECU will retard ignition timing and cut boost drastically).

the power difference is pretty small. What is it 3-5 hp?

I looked into this. 91 was easier to get then 93 for my DD routes, was not worth the hassle to switch to 93.

just my opinion.

Did you end up flashing GST basemap? How did you like it? what noticable performance upgrades did you feel??

I actually just got my Tactrix cable today! So no I have not done anyting yet as I am very newbish at this and trying to figure out how to just log by itself first. I will inform you when I actually flash.

thanks,

Ok so Huston we have a problem. I tried to just save my stock ECU rom. It seemed to work fine after I unplugged it however I know have a service engine soon light on! :confused: is this normal how do I get rid of it? Also is the car supposed to put up a bunch of warnings while the openport is reading the ecu??? Please help!!!!

No you don't, but when you get into self tuning and logging, it will become your new best friend lol

Very true.

A crude work-around is to do dyno pulls where they have tailpipe sniffer that can approximate the air/fuel ratio. From experience the shop should be able to tell you roughly how far off their sniffer is from the actual value.

I did that on another car, and the results were fair.

OK guys so I got my Ultimate racing boost pill over the weekend and installed it and re-mapped to the 93 oct with boostpill GST map and all I can say is WOW :eek: It is amazing :D. Below is the "stock pill (RED)" GST map on my vs the "boost pill (BLUE)" map on my car. Same tank of gas and everything so its should be a good comparison of the gains.

Nice improvement over the stock pill base map!

Curves are much smoother.
