Default Another Learn View..... CHECK THIS ONE OUT!

Whats up everyone, to start this off I just purchased the car about a month ago with the following..

1. Intake
2. Catless Up
3. Full 3" catted exhaust
4. Big 16g
5. Front mount
6. Prosport Wideband

The PO stated that the car was OS tuned to 23psi. Im new to Scooby's but not to turbo cars, I used to own a 98 Eclipse GST and also used a Tactrix cable but never got to tune with it. I haven't beat on the car at all and plan to keep it that way but want to tune it to my liking rather than trust someone elses word. Ive attached a pic of my learning view, please keep in mind that there are still quite a few things I need to do:

1. Verify injector size, are the factory injectors pink? If not mine are, suggestions?
2. Boost leak test
3.Compression/Leakdown test
4. Change plugs

Let me know what you think!





PS I did reset the ecu and am going to do another View tomorrow.

Either maf or injector scaling is botched or you have a leak.

IAM is good

Being on a big 16g I hope you're not on factory injectors especially with a 2.0l.

Guessing you've got pinks?

Clean your maf for starters.

To add to my first post the snap ring did let loose on my bov and I've had to fix it twice. I believe the synapse bov to hks adapter is too thick which in turn isn't letting the snap ring seat fully. Anyone else have that problem and could it be why my readings are what they are?

Got that backwards. Rich at idle lean in boost. The learning is correcting for that lean condition in the a range so it's pulling fuel . C-d the ecu is adding too much fuel.

Ill point out the obvious.

You need a new front o2 sensor. Change that and reset. See what it does

I think the problem was that the Bob popped off causing a peg rich condition down low. I'm going to recheck in 10 mins and will post back. It let's out a backfire after shifting if I shift from first to second slowly. Due to being rich correct?

I'm going to post my map for input even though I haven't logged yet.

Will log tomorrow, parameter suggestions? I've seen mixed on what should be logged. Flkc, mafv, throttle, knock, etc etc....


Thanks again!

I was seriously wondering that ^ but I couldn't get photo to load on mobile again.

^ And yes rich, backfires are unburnt fuel combusting in the exhaust

I checked again and the injectors are pink im assuming that theyre sti's? Also the tuner has my injector scaling to 550cc

Wondering how to attach the Rom file in the post?

That's what I get for drinking and posting...

In that case, a bad FPR or a leak in the FPR reference line could do it, among other things.

Will do, I know he tapped the boost gauge off of the fpr. Perhaps that's contributing.....

@ Sidewayz why is it that you think I need a o2? Could it be the fact that my Synapse bov to hks flange adapter doesn't have an O-ring? The PO never had one in between the bov adapter and the flange!!! Ill be purchasing a O-ring asap.

Edit: Installed the correct o-ring and she holds up to 22psi! I wont be hitting that psi again though without making sure the tune is correct.... AFR stayed in the 11.'s though...

This was from today after a reset, the previous one was after my BOV popped off of the pipe and I had to drive it 100ft to the parking lot of a pepboys...

A LV table can be misleading if you reset the ecu frequently. Insufficient data in some load ranges can make the correction % inaccurate.

Not sure where to find this but how often does the ecu determine these values?

Depends on how often you are in particular cell while driving.

Can you give me a for example. For instance I drive 45miles to work everday hardly ever going above 5500rpm. So youre saying that staying below 5500 whatever the last time that I went above it the ecu stores correct? I do a lot of 2500-3500 highway driving, with the occasional stop and go up to about 3500-4000 in 2nd or 3rd...

The engine speed does not have much to do with fuel trims, it's mostly manifold pressure, or more accurately, engine load (g/sec) that play the main part in the fueling calculations performed by the ecu. For example, peak boost at 3k rpm will be a higher engine load than no boost at redline. Try to vary your right foot and hold gears longer if you want to gather data on all the ranges of the fueling trims

Will do and to touch on what you said is it the highest values that it stores or average? Or is there a particular rhyme or reason of what the ecu stores?



Thanks again!

It's the accumulated average. I'm not sure what the time base is, but it's pretty long. It can take days for a change to make its way into AFL.

Ok so hitting a load range in D for a couple seconds might not show correct?

A couple of seconds? Absolutely not...try a couple of hours.

Ok, so with that being said wouldn't I need to hit that particular range @ say 5500rpm for minutes at a time over the course of a month to show values?

Perhaps I have this all wrong but from what I'm gathering in order to fill every cell id have to hit each one for long enough periods of time that the ecu shows a value....

Thanks for being patient with me lol... I'll get it...
