ROM TUNE + Boost Controller

[IHeartRPS13]

Sorry i'm new to this ecu tuning thing, forgive my noobness.

Ok, so i was talking to some people about rom tuning the sr20det but they said it would be better to get a megasquirt since it would allow me to tune for different boost levels if i needed to. What do you guys think? If i had a JWT or Enthalpy rom tune and i want to add a boost controller would it affect anything? too rich too lean? Lets say the rom tune was for a gt2871r, 740cc, z32 maf, ect. and i want to be able to change my boost when i drive lets say 18psi for track and 7 for street) would that affect anything? or do i have to constantly leave it at 18psi.

megasquirt? i havent heard of some one running that in a while. its useless in my opinion. stick with your rom tune and BC, if you have the spec B you obviously have 2 different settings. low and high. if your racing some one then your obviously only going to run your high setting not your low and regardless of boost level your ecu will adjust everything accordingly..

ull be fine with jwt or enthalpy... your maf reads the amount of air coming into the motor so the ecu will add the apropriate fuel.. so more boost the maf reads more air and more fuel is added to compinsate

ah thanks that helped a lot. i forgot about the maf factor in this.

I have an enthalpy rom tune and i have a pro spec B. but it was tuned on the high setting of 16psi so when i have it on low (10psi) the ecu and the maf can compensate for the change so the car isn running too rich or lean.

His boost controller has two (or more i cant remember if the B has two or 4) preset boost levels. One for high boost (his 16) and one for low (his 10). He set those when he was tuning his boost controller.

The MAF will correct itself.

Plus, JWT does remaps. That is what it is. You cant tune it from home tho, and the only way to correct it for later mods is a reflash, which i believe is 100 bucks. Try looking up Nistune. Depends on if you are seriously going to be doing a lot of tuning, but its worth a lookup. Will cost you because you need to get it tuned by a pro.

our answer has been yes in the last few replies....critical thinking skills bro...use 'em

Calm down Jeez. Why don't you spare some of those button punches from being wasted here and put them to use in say, an email to JWT or Enthalpy asking them your question?

You asked if your running a ecu which is rome tuned for 18psi if you would be able to run different boost levels safely. I replied in my first post " regardless of boost level your ecu will adjust everything accordingly". No i own a coupe with a modded SR which I actually work on. As for the "kid" comment, I drive 20,000lb tactical vehicles for the US Marine Corps.

ah thanks that helped a lot. i forgot about the maf factor in this.

How exactly do you forget that you have a MAF? I guess some one has to remind you that you have to change your oil every 3000miles if your using synthetic too uh?

Thank you. Now stfu.

It doesn't matter what boost you run on a MAF car. Injectors, and MAF type is about it. However, if and when you datalog a run to send to JWT or Enthalpy, do it on your highest boost level, to get a full reading on your parts.

As for the "kid" comment, I drive 20,000lb tactical vehicles for the US Marine Corps.

There are plenty of kid's that do the same thing you do, across the military. It doesn't give you the right to throw your occupation around like it should get you any 'overage' over another person. Not trying to rag you, but (as a fellow servicemember) pointing that point out.

[mistamacadamian]

lol...when i said 2 different settings i was relating to the spec B BC. its not 2 separate maps, its just 2 different boost settings which you adjust in the car. your MAF will send information to the ecu, the ecu will decide how much fuel to inject for the amount of air regardless of what boost your running. not too hard to understand. And I did graduate buddy, seems like your having a hard time grasping the concept of a simple question. Which in searching for 5min the answer could have easily been found. They made a website for Community college boys like you http://www.google.com. Its ok though sweet heart, keep boasting about how much you'll be making b/c life is definitely all about how much money you make. I enjoy my life and will pursue my dreams as I already have and will soon be a fire fighter after I come back from Iraq:) And I know cody, I did train with other young Marines as myself and my current unit is filled with lots of young Marines also.I was simply throwing that out there to show that I wasnt the kid he was expecting, but I do know a decent amount on how to work on vehicles wether its my 240 or LVS. Just wanted to "point" out that point.

Maybe you should spend a little time on the suggested website mentioned above... and find out how timing and fuel maps work. Then maybe you'll know there's not 2 maps, and that there is no answer to your question without seeing the timing map your running, or asking the guy who tuned it.

[mistamacadamian]

if you cant even attempt to find the answer i doubt you would even be able to comprehend timing maps, much less graduate from your local community college. there is no answer to your question b/c regardless of the boost your running when your flooring it, your still running the same timing values of the last cell on your map. i like the cute insults though, you most definitely graduated from high school with a GPA of 2.0-2.2

i could probably give and answer but i dont feel like reading through all of that bickering lol

[jr_ss]

Once your ECU is ROM tuned, your car falls back on the maps (i.e. fuel and timing) for a given load/rpm and adjust it from there... It's all taken care of with the ROM tune, plug it in, forget it and go. You don't have to adjust anything.

Now quit with the childish bullsh*t. Everyone has given you an answer, whether it be exactly what you wanted to hear or not...

Do some research man, there are plenty of threads reguarding ROM tunes, it isn't exactly a new technology.

Ive had fun being humored by you, my friend actually was the one who shifted from 3rd to 2nd when he was racing a z06 while we were driving. This is my last reply and I am surprised people have been this nice to some one with stupid *** replies such as yours. Go play in traffic, your wasting oxygen.

wzntha seems like a spastic retard.

Ha, thank you. I was just doing some searching and came across this uber dramatic thread. Have you cured your issues yet? Seems like maybe you had some problems at home. :p
