Tuning Alliance

Latest rounds of maps/updates sent this morning! -Brian

Keep em coming! We've streamlined our internal processing of etunes, so communication is at an all time high! -Brian

I would get your car tuned sooner rather than later, can't be running that turbo and other mods without proper tuning. Shoot us a PM and we can get you setup on the right path. -Brian (tnx max/battle for the recommendations)

We are very frequently in MA tuning at Enhanced Street Performance !! Mike's also originally from MA. -Brian

I'll have him take a look at it. -Brian

Looks nice!! -Brian

I'm not really in love with that method of limiting the a/f learning, as you loose a break point the in the table, but I suppose it'll work.

What about disabling CEL's, I noticed in a 03 wrx i was doing the other day, i was still getting pending codes. They won't throw the actual cel, but is there a way to shut them off in OS?

Sure I can go into detail about which tables are missing and why they are extremely important. It is also possible that I don't have the best definitions available for OS, but tracking them down can be a challenge in itself. So forgive me if that is the case, but based on what I have here are my findings. There are benefits on the logging side, as btssm has done some great work and can support custom sensor inputs, being able to log a wideband real-time in the same log is a beautiful thing. A/F Learning #1 maf airflow limit - This table limits the a/f learning below a specified g/s. If you set CL delays to 0 and the car is fueling lets say 11:1 afr at 100 g/s, the ecu will learn a negative value over time and begin to lean out the high end. This can be very dangerous if learning values are not monitored closely over time. A/F correction #3 limits - This allows the ecu to make fuel adjustments off of the rear o2 signal for "improved" emissions. This can also sneak up a week after the tune and begin to alter the fueling throughout the entire range. Even with a disconnected rear sensor it is advisable to disable this ability of the ecu as an variance in voltage will potentially alter fueling. Target throttle angles (idle airflow target) - Some engines require increased throttle opening to return to idle smoothly. They often will dip down to 300-500 rpms when you let of the throttle, then come back to target idle speed. They will often learn to give additional angle over time, but some cars will even stall due to this. It generally is only a problem on big rotated builds with after market intake manifolds. There are also other less important tables, for example waste gate duty compensation for coolant temp. I may add some more info later, just need to do a few other things at the moment. ~Mike

Word on the street is Tuning Alliance now can tune/sell delicious flex fuel kits more info to come.... -B

Absolutely! We stand behind what we say! This is just for "new customers" -Brian

ANNOUNCEMENT As per Mike K, we will now no longer be taking in new Open Source etuning customers. Cobb offers a much better tune by giving us access to more tables. -Brian

Thanks!!! Woot Time for a TA tune, shoot us a message to get started -Brian

Hey guys, I have tuned a few of these recently and have seen varying results. I was asked by some customers to comment and thought this may be helpful to others. I haven't had much up and close time with a VF54 personally, but its seems the wastegate sizing is a bit too small for the system.I would speculate that variation in the turbine castings is causing some to flow better than others and ultimately work okay while others consistently creep. I have seen the same issue in 15-16 STi's, when a high flowing downpipe is installed severe boost spikes occur (23-24psi) regardless of boost control or flapper position. In extreme cases I have implemented throttle limiting to decrease airflow and boost into the engine. This is the only easy fix aside from reverting to a stock downpipe. Problem: Insufficient Wastegate flow (mechanical boost creep) Cause: High flowing downpipe Potential Fixes: -Wastegate and/or turbine porting (requires turbo removal) -External Wastegate (Not practical on 5th gen) -Electronic limiting of throttle -Restrictive/stock downpipe Other suggestions: -FMIC (may reduce boost and reduce charge temps for a happier engine) ~Mike

Hey guys, just wanted to see if anyone would mind posting any review on here about TA on NASIOC. We've recently re-activated our vendor membership there, make our legacy game known!! Appreciate any help in advance guys, you're great! http://forums.nasioc.com/forums/showthread.php?p=44515583&posted=1#post44515583 -Brian

CTLegacy lol -B

Although word on the street is, TA is looking for potential locations

Special services to a special member =) -Brian

How many miles on the plugs? 6 months of revisions included if needed. Shoot us a PM with your email, and we'll send over a paypal invoice to get started. -Brian

Not a problem!! We do sell parts too! So if you want anything, hit us up more than glad to help out. -Brian

Currently we do not tune 4 cylinder n/a legacys. That being said, no you wont see much of an improvement. -Brian

ETUNE PRICING Stage 1-2 200 Stage 3+ 250 Send us a PM to get started the last tune you'll ever want! -Brian

Flex fuel requires two tunes. One on pump, one on e85,then the program will adjust based on what it reads from the sensor for % blend. -Brian
