Curious about ECU tune stage 1

[Jedz123]

Hello fellas I just recently finished my EG33 swap into my 94 Legacy FWD. I was curious about the ECU tune stage 1 upgrade. I was wondering if it was worth the investment for you that have done the upgrade... thanks

Yes, its worth it.

[SomethingElse]

+1..

It kills gas milage but I dont think your worried about it

I noticed that ECUTune's site lists it as out of stock and doesn't seem to have any information as to whether it will be back in stock or not. I'm not going to be doing massive modifications to my car, so spending extra for Stage 2 is not really a good move on my part.

LAN, when can we expect new Stage 1 kits?

I've heard good things and bad things about it. I dunno what to do. It'd be cool to have a bit more power, but not if it uses an extra 5mpg.

NO I'm not worried about it... lol

How much power could I potentially gain from this upgrade? From what I understand is that it really helps your low end... which is cool but I already have enough traction problems. LOL... not exactly a bad thing! It also raises the rev limiter up to 7,4000rpm...is that necessary? Is that safe? sorry guys for the constawnt q's I'm just curious thanks so much!

I do not see why it would be necessary. Actually, it looks pointless. Look at the dyno chart they provided.




I still wonder about this dyno chart. The purple line looks as if they were able to dyno from a low rev range. The green line looks like it was just coming out of a shift from my experience. The green line is completely vertical.....almost V-tecish. I dunno!

The raised redline is poinless for a stock SVX engine, but 7,500 shouldn't do any mechanical damage. I suspect the valves starting to float and the lifters starting to colapse would remove power quick enough ontop of the standard puke-N-die of the stock cams.

I have it installed but I'm not a fan. I don't feel a difference, but it's usefull if you want to switch between premium and regular gas.

A valuable practical reference for sure.

The question now obvious is, on what basis is it useful, given that it is reported to increase fuel consumption? I run on regular and there is no indication that the OEM set up does note cope 100%.

The graph presented is most certainly very suspect. Placebo reduces the wallets of many, to the advantage of a few.

I talk to LAN alot. The purpose of the raised rpm was for the guy's that have converted to manual. In an auto It wont do much, because the tranny is still going to shift at the same points.

:/ you guys act like this is claiming to turbocharge your car. IT dropped a few tenths on my querter i can vouch for that from the stock 92 map. Its not a turbocharger, and it dosnt cost a grand.

Four years ago when stage 1v1 was being developed and that plot was posted what it was was clearly labeled and discussed. That huge dip in the begining of that plot is not the best case scenario for a stock car and it was never claimed to be. That plot is of the intermittent hessitation that occurs when it goes too lean at "tip in" and and pulls out huge amounts of timing. It's an intermittent problem not the norm every time you press the gas but it is real and does happen as we all know. It does not happen with any version of the stage 1 software (you are welcome). The best case plot for the stock software was also posted. Low rpm performance of stage 1v1 was way better than the best case stock plot as well--of course that was 4 years ago and we are on v5 now.....

I have no idea why you want to grab onto a 4 year old plot and act like it's something other than it was claimed to be and suggest I've posted something that is "suspect." (but that to me seems suspect)

very suspect? No it was thoroughly discussed at the time and what it was was clearly identified. Everyone who actually races their svx and has real time data for it and has installed any version of stage 1 has found real improvements. That includes the admin of this network who competes, i believe at the national level, and ovbiously has very detailed time records.


Increased fuel consumption? I certainly haven't heard that before. The general consesnsus I've always heard is that the fuel consumption is the same. The power you get from the extra fuel under throttle pays for the fuel. The afr is not richer at cruise and hence can't possibly use more fuel. In the last and current version of stage 1 timing at cruise was increased--more timing at cruise equals (anyone want to guess)....improved fuel economy.


I think your repeated, thinly disguised insults of my character and work are more objectionable than your recent direct outburst of insults. Whatever chip you have gotten on your shoulder from the misjudgements you have made and perception that I was daring to question a diagnosis or comment you had made IS quickly eroding my perception of you. If you really want to continue down that road I'm not one to be shy you will hear exactly what I think.

More power at the lower end, better timing tables, smoother power, AND BETTER GAS MILEAGE!
Thats my ECUTune experiance, and I've had 1V4, 1V5, 2V5, 2V6, and soon will get the 2V7.
I run with the Subaru select Monitor watching the advance, and retard, and I am VERY happy with the results!
