Dealin with 2 bar problems. Need help~

[redhotjamedjimi]

I just got hptuners a week ago.

i'm trying to fake a 2 bar to compensate for different boosts pressures i want to use and lessen fuel problems.

Im trying to rescales the values in each column and row. but when i open the file in excel (high octance spark advance vs map) it is delimited and has no row or column labels to double. yet "shifted" says to double each value. i see no values to directly double. and all my attepmts to put my own in makes the load option for the table to go "invalid data input."

Someone please help me or tell me if i cant do this to my vehicle. im probably missing something. i need someone's advice who has successfully done this.

[redhotjamedjimi]

so no help yet but...

do i have to change the table axis physically or just make the table valuews different and put the 2 bar map on and itll read fine?

Someone check out my different changes. any tips?

[redhotjamedjimi]

I'm doing this as we speak so if anybody at all wants to help me out legt me know

[Bill@HPTuners]

im not sure about all of the tune since I've never done a 2.2 before BUT I will say a commanded afr at WOT of 13.75:1 in a boosted application might not be the safest bet...just a heads up

[Bill@HPTuners]

also looks like you might still have a 92mph speed limiter in place...look under spark advance

[redhotjamedjimi]

i made the pe table 1.1 across most of my boost band to overcome any problems with lean and temp is this bad with a 2 bar?

[redhotjamedjimi]

this is what is going into my truck tomorrow for 2 bar

[Bill@HPTuners]

read how to tune pe in your truck man...in that ect range you have a base commanded afr of 12.5:1...that 1.1 is a multiplyer meaning 12.5*1.1=13.75:1 afr commanded

to quote the help file for the PE multiplyer "lower numbers are richer"

personally to make it simple I'd probably just change the base afr to stoich to make it easier for me to understand, then just enter a PE table that im used to

[redhotjamedjimi]

i fixed that. thanks for the info. besides that nothing out of the ordinary then. i hope this works out.

[Bill@HPTuners]

eh, hard to tell without a stock file to compare to to be honest. And personally I've never done a 2 bar on a stock OS so im not sure what would need to be done just knew your pe was off so figured i'd let you know before something goes boom.

[redhotjamedjimi]

heres my stocky note 310cc over 178.5cc stock? i think

[redhotjamedjimi]

i tried the 2 bar thing today. wasnt even close i guess. someone let me know how to make the ve tables close enough to pull this off and how to make the idle work. do i need the pro and a wideband? as for now im one barring it.

What size/specs for the turbo, and how much boost are you running??? Also, you are aware that MAP controls the timing, not fuel on this platform, correct???

[redhotjamedjimi]

I have a 45 trim stage 3 t3/t4. running 7 psi. trying for 10. i know about the timing and not the fuel.only but today at full vacuum at idle it was reading 22 kpa then i put my 1 bar on and it read 44. the table at twice made the lowest column 40 kpa so how would i tune a idle at 22 but let it warmup? plus my idle will sshow the timing goes crazy between 20 kpa and 30kpa so its hard to say what is the stock im aiming for. any help would do. ill tell you anything.

[redhotjamedjimi]

I got my 2 bar tune to work surpissingly well if anyone wants a model to work with or anything.

Or if anyone has anything to add to my tune or questions where it all came from ask and ill happily answer.

[zinner]

Can't load the tune with 2.1.14. Says send the definitions to support...

[redhotjamedjimi]

got cha....

Fueling isn't controlled by MAP? How is is controlled then? I'm going to guess some sort of TPS based controll???

I'll be putting a turbo on the 2.2 in the Xtreme here in a few months, and need to get reading up on this ASAP. Can you point me in the right direction or offer some links to go read?

[redhotjamedjimi]

haha map is for timing. all fueling is in Volume efficiency (Tps %) in open loop.

http://minimopar.knizefamily.net/perf/turbo.html thats where i learned most of whats need for a turbo kit etc.

besides that theres alot of custmoizing manifold exhaust. some injectors adjustable fuel reg. i changed my head gasket out first with a newer better one those stock ones are problems.

there are cheap intercoolers on ebay that are only 100 bucks dont go spending 400$ wtf.

also a guy on ebay that does 2.2 cavy manifolds but he can leave off the turbo flange so u can put it whre u want it.

your fine on a 1 bar to liek 7 in my opinon unless u want to have a more extreme advance in the 0-3 psi range or something crazy.

if its a manual got o horsepowerfreaks.com for spec clutches and or flywheels.

any other questions ill gladly help.

i know i had to searchthe internet for months to find what i needed to know.
