How to tell of my car already has a tune?

[Captainstabalot]

Hey guys new to the forum and got my car a week ago. I got it used from a dealership but whoever owned it had already done some mods. Trd exhaust and Springs and K&N filter. I don't feel the torque dip that this car is notorious for so I'm wondering if he did a tune of some sort. How would I find out if there is already a tune on my car?

Read the rom and compare it to stock. Though, the best tune in the world won't remove the torque dip without headers.

Sorry for my ignorance, but like I said I just got the car and have no clue how to check the rom

Is this the first time you have owned an FRS? How do you know what you're feeling is the torque dip and not just a general lack of power (if you come from a more powerful car)? the torque dip in a dyno graph doesn't necessarily feel like it looks in real life.

I don't think there's a way to check the ROM without actually purchasing anything such as an OFT or EcuTek cable/software.

Damn it well that sucks. Ya this is my first frs and my other car is a E55 amg. Two totally different beasts.

I used to have just the TRD exhaust, and even with a tune I could feel the torque dip. It's pretty noticeable.

Ok well I guess I will assume I need to spend some money then. Now I have to choose oft or ecu

When you start the car cold, what RPM does it rev up to and sit while it warms up.
Most tunes modify this to rev to lower RPMs to not be so annoying.

The OFT stage 1 tune almost completely removed the torque dip on my car (at over 1 mile high, 91 octane, etc. results may vary)
AND the ROM ID is the same as it was before the tune.
So you would have to pull the ROM and do a digital compare against the factory ROM to tell if it is different.
OR open them both in ROM raider and do a compare.

It idles pretty high. Not exactly sure but I'm guess 1500rpm. I have a lot of reading to do so I can understand this romantic stuff and rom raider

well, I think this might be a way to see if you have OFT: 1st gear clutch in and rev. see if the rev limiter is at 5500 (this is the stock OFT launch control RPM). if it is, then you have OFT. if not, then try using the cruise control stalk to select a map. if that works, then you have EcuTek. here is a guide for the map selecting for EcuTek: http://blog.perrinperformance.com/ho...-perrin-tunes/

Thanks I'll try that in the morning and let you guys know. Appreciate the help

After driving for while, check to see if rpm drops under 700rpm while idle.
Correct me if I am wrong but stock tune does that shit and feels like car is going to stall by itself.

If the previous owner flashed it with an OFT, unless the owner is an idiot, he or she wouldn't flashed it back to stock and unmarried the tablet from the car. Otherwise, s/he'd be stuck with a useless tablet with no resale value.

Where are you? I can read it with open port.
