electronic boost controllers and tuners in one box?

[zxmarekxz]

Hey, I was just thinking that I haven't seen anyone talk about an all in one tuners for mustangs where you have pre-programmed maps with various boost levels. For example, you press one for stock, and two for high boost and associated tune from inside the car.
Is stuff like that available for turbo mustangs?

I think it would be cool to switch between various tunes and boost levels on the fly..

 

[JeremyH]

Boost levels yes, tunes no.

 

[zxmarekxz]

Boost levels yes, tunes no.

cool, thanks.

 

[JeremyH]

Yup our pcm cant do the flip chip stuff anymore so you will have to take the 1-2 minutes to swap a tune with your handheld. But yes ebc can do boost multiple settings that change at a push of a button, you can adjust boost by gear, rpm etc.

 

[Full_Tilt]

Theres no reason to have multiples tunes for different boost levels. As boost changes you move into a different part of the map, so if tuned properly it will be fully optimized for any boost level below what it is tuned for.

 

[JeremyH]

Yeah there is, its called for safety. I have a street tune that i run 9-12 psi on and I have second tune that I can run 14-18psi on.

Id rather have the tune already setup to command that extra fuel and little less timing at higher boost levels then hope it adjusts on its own.

 

[Full_Tilt]

But the tune that is tuned for 14-18 psi should almost just be a continuation in the map from the 9-12 psi map, right?

 

[JeremyH]

Just wot fuel and timing adjustsments. So yes I could run the 14-18 psi tune all the time. ( i run 12 psi on the street ) but at wot it would be really rich and effect gas mileage during street driivng as well. I have 3 slots for tunes so why not have a couple tunes setup exactly for the boost level that I intend to run. The only time I would load up the other tune is for the track. And I definetly want to make sure the a/f is dialed in for the that.

Is not needed, one tune can do all.

 

[JeremyH]

Well of course you could do it with one tune, but like I said, it aint happening, not for me anyways. Im not going to take a tune that was set for 10-12psi and crank it up to 18psi on the boost controller and have at it. No thanks. I have the low boost tune done long before so no reason to get rid of it just because I have a newer one set to 14-18 psi. I like having them both and will keep them.

Jeremy I don't think lito is saying a 12psi tune will handle your 16psi. But your 16psi tune would handle your 12psi just fine. I mean if you think about your wot fueling being an issue, wouldn't it be an issue for us in 1st gear as we don't make nearly the same boost as we do in 4th at wot. With that theory our 1st gear hole shots would be running really rich? I have no clue i'm just talking out loud. I just think about the cars that do the gear selected boost levels. They are still on the same tune no matter what gear they are in so how are the wot fuel tables any different between gears?

I had asked mike once upon a time (maybe on my first trip to his shop before I saw my shitty 417hp) and I had asked him if I wanted to back the boost down could I do that safely on the tune he was giving me and he said sure.

Whats going to happen if some nasty head cammed z06 rolls up on you on 64 and you want to throw 16psi in it? No time to change your tune then ;-)

Regardless if you want to run multiple boost levels on one tune or not, it can be done and done safely. It's all in the tune. The only thing is there is sometimes a bit of drive ability issues when the software jumps between tables. Most people rarely notice it when done properly but it can happen and rarely is it a risky issue. Usually the result will be that the tune is a little rich in a certain spot and you really can do anything about it.

Basically while your tuning the car it gets set up to where your transfer tables for your highest boost level are towards the top of the table, then you have your additional boost levels in between that and your normal driving area in your tune(the area where your not seeing positive pressure) Then you just tune the car for those boost levels and make the necessary adjustments so that everything is where it needs to be for a/f and timing. Now when your driving at 12psi it would be hitting in the middle of the table and when your driving at 18psi it hits at the top of the table. The trick is trying to hit all the little in between blocks so that the transitions between the two are smooth. It's because of this style of tuning that i was able to run 14psi in 1st and 2nd gear, 18psi in 3rd gear and 24psi in 4th gear in my focus.

Like i said it's all in the tune. But it can be done. I have had allot better luck with blow-through setups doing this than with draw-through like what is stock on the mustang.

This has been my point all along im not going to turn up the boost on my lower boost tune. But yes its okay to turn it down on a higher boost tune.

I run what I got, I will continue to leave it at 12psi. I dont run 16psi on the street even to just play around so trying to run 16psi and race would be an even worse decisoin. Maybe Im one of the few people who is content with 500-550rwhp on street. Thats enough for me and a handful already.

The higher boost would be for the track thus it has its own tune, and shit last time out I didnt even try it yet as I still want to see the best I can do at 12psi first. Plus I kept blowing couplers apart at 12psi. lol

I was talking along the lines of what jodadejss06gt said.

There is no thing such as a XXpsi tune.

Actually the PCM doesn't even know (basically and at least for the major part of the fueling calculation) the boost you are running.

 

[JeremyH]

Just playing it safe, its what works for me and what I will continue to do.

 

[jodadejss06gt]

Hell yea Jeremy, so you have a tune at 655/582 and you haven't even felt it? I mean my 471 is hella fun and can get me in pleanty of trouble. 550 would be even more redic. 655 well thats like you said a little crazy! I'm probably not making enough boost to do anything to couplers but I haven't had a bit of trouble on them.

 

[JeremyH]

Just a couple hits on the way home from getting the dyno tune done. But its worthless on street tires for sure. And even more worthless under 60mph.

Its funny I've never had any trouble on the street or dyno with my couplers but at the track I kept blowing them apart.

 

[lito]

Whatever makes you comfortable and/or happy.

Just commented for completeness as that is basically how it works, a single spark table will work for high and low boost, also the fueling will work, and it will have zero influence on mileage, just a complete tune for the max airflow and it will work everywhere.

 

[JeremyH]

Makes sense. In my case i did it backwards tuned for low boost. Then went back later and tuned for higher. So i still have the low boost tune which is all I need for driving to and from work ocasionaly lol

great info, thanks guys
