Although it is possible to tune it with the SAFC, there is more power to be had with a mail-in flash fine-tuned with an SAFC. I initially had my car tuned with just the SAFC, but then got a mail-in flash over that and noticed a huge increase in midrange power (3500-5500 RPM). The top end remained about the same. I did log a few runs to determine my times from 40-60 mph in 3rd gear and if I recall correctly I picked up 2 or 3 tenths of a second with the flash (~2.5 seconds down to 2.2). Hope this helps with your decision.

Another thing to remember is that he has an 03, not an 05. The 03 factory tune has less aggressive timing than the 05 therefore reducing the potential gains with an SAFC alone. Your results with the SAFC have been quite impressive, but I'm not sure that they are possible with an 03.

I did not know this had been confirmed. Do we have confirmation of this? I'm not arguing against it, but I just hadn't seen any empirical data.

I agree and stated as such previously. If he's willing to spend the extra money, then this can be achieved, but I still don't think it solves his "problem." If his car isn't running well and already pulling over 300whp (even on 91), then his SAFC is not tuned correctly (if at all). He should verify this before buying bandaids to fix it. Plus, if it's not properly tuned now, it won't get properly tuned after the flash either...

 

since we're talking about such things what do u tune for when you are tuning for the intake. I thought the MAF would account for more air??? I have heard numerous times that intakes are worthless unless they get tuned for.

 

Keep to the topic. Also, your question has been asked thousands of times (search).

 

If you plan on doing more mods soon, do a lot of racing, etc, I would just get the proper devices and tune your SAFC. Even if you have to get help from a professional, I would do it. If you plan on leaving everything as is for the time being, I would get a custom tune from Al or TT, etc. The thing that I really want to do is tune my own car. Since I've installed all the parts on my car all by myself, I wanted to tune it myself too. This could be risky, but in the end you will have a car that you personally were able to build all by yourself. I have a lot of respect for those people, not to say getting some help is bad, I just think it would be nice to have everything done yourself.

 

listen to this guy!!! Get an SAFC and get it tune from some dsm peepz or let them teach you. Dr gray from socalevo got 348 hp/ 345 tq w/a safc http://www.socalevo.net/forums/viewtopic.php?t=9180.

if u R going for a flash read my sig, but I prefer safc. I got 284hp/286tq on my 05 with just a catback, gut cat, and safe tune w/a safc.

 

Nice numbers for those mods moogle I might look into it I have an 05 as well

 

A little off topic, but not really... Moogle, what did dynoflash do to your car that makes you not like them? I'm sure a lot of us would like to know.

 

OK, so numerous things come to mind after reading this thread:

1: Although it may be in my mind, it's possible my cams were installed incorrectly. I say this because after the install, I noticed some gains up top but every once and a while, the car will run like complete s$%# while trying to accelerate (feels like it's chocking) and once I let off the gas and give it another go, it seems to run fine. However, lately it's been having this symptom more often than not?!?

2: I've done my homework, which is the reason why I bought the AFC in the first place. Now I don't have any type of data logger which is why I haven't had the chance to do too much. The last thing I need is to hear my engine falling apart. But I've read that an AFC on top of a flash can't do any harm at all.

3: Since TT isn't too far from Lancaster, I'll be making the trip down there to have the car's issues diagnosed and the ECU flashed.


I'm hoping my problem is due to lack of proper tuning and not incorrectly installed cams. But nonetheless, I'll do a pre-flash/tune dyno run followed by a flashed/tuned run to see how big a difference a good tune makes.

Thanks for all the help fellas.

 

To the guy who started this thread - if you want to try the Dyno Flash and see how it works you can try it risk free and report back your results. If you are not fully 100% satisfied I wont charge you a dime and I'll flash you back to stock.

You have nothing to loose - give it a try and see how it works first hand.

 

This is true becuase cars run with the SAFC typically pull loads of ignition timing down low. The stock timing tables become very advanced when you are pulling out significant percentages of load on the maf signal. In many cases they wind up with negative ignition timing or zero degrees advanced. This is why many SAFC dyno sheets have 20 - 30 less tq than whp, unlike the flashed dyno sheets which have equal tq or slightly more.

In addition - the flash can access boost control in the stock ecu, fuel cut, rev limiter and other critical features such as the dual fuel and igition maps in the ecu.

Witha safc as the maps switch in the ecu your tune is consantly going on and off - its a set percentage off of a table which switches back and forth between high octane and low octane maps which are changing depending on operational conditions the ecu is recording.

 

CANT BEAT THAT!!

 

I have a 2 week test drive money back gurantee with every flash. I have very few people who don't want to keep the flash, probably one or two out of 300.

 

Sounds good, but I still need to make sure my only problem is not being tuned.
