The only changes that I've made are my injectors, and suddenly it wont hit anything above about 180-200 load cell. Car feels decently normal, although I expected more power out of the new turbo, I am however still dialing it in and I can't do a very good job if the car wont hit the load cells that it's supposed to.

I will provide my map (which is by no means done) and a bunch of logs....one of the logs will be the old 680cc injectors, I will provide the map for that as well (which was only temporary)

Any help would be greatly appreciated.

Any change in IPW or MAFhz on logs?

 

um....didnt look, lemme take a look, I know that IPW came way down because the injectors were damn near maxed out


as far as MAFhz it gets to a certain point and levels out because I assume it's maxed.

 

Are you reading the LoadCalc (which will be wrong because of the larger injectors) or cross-referencing RPM / timing?

I looked at the log (880cc2) and timing table and checked RPM/Timing and I see you hitting load 230 @ 4500 rpm (11*) and load 270+ @ 5000 (9*)

Log 880cc4 you are hitting load 260 (10*) @ 5000 rpm and 260+ (12*) at 5500 rpm , 260 (14*) at 6000 rpm, 260 (15*) at 6500 rpm.

With that turbo you should really rescale your load table for higher loads.

and what the heck is up with your fuel map?

 

IPW is much lower then the MAF reading on the newer injectors.....

 

I told you that It was a rough map.....I was really only hitting the WOT parts....I see what you're saying....

Where did you come up with the load table numbers? by cross referencing the timing numbers?

 

Hi

Are you able to log real load? This might be better for a setup that is not near standard. You can mod your ROM to do this, I have done a couple but the real guru would be jcsbanks on here.

If your interested, I've just rescaled your fuel and ignition maps to read to 300, Like razor lab said, what the heck is going on wirth your fuel maps? Adjusting the closed loop areas will do nothing to the actual AFRs as the ECU will use the O2 feedback to try to get to 14.7.

Ok after realizing that it's just not reading correctly in the logger I started tuning the way I used to and made some signifigant changes....I still need to log it as it is right now because I leaned out the top a little further, but data log labs was saying 486hp....from 425 that I was seeing on 21psi.

so atleast I'm making some progress, I think with it leaned out up top I'm going to see 500hp on DLL, or atleast I hope...knock counts were way lower now that I figured out where to adjust timing and fuel.

I think I pretty much have it figured out, but you're correct when you say I need to rescale my fuel/timing maps, Ill do that soon.

Thanks for the help, I hit the dyno thursday so I'll have real numbers, hoping for over 400 on the mustang.

 

Yup, which will be accurate unless you are knocking or off the load scale. You really should rescale it for that turbo.

 

Yeah I'm looking for the how to right now. I really didnt see a huge improvement from leaning out the AFR's up top, honestly the tq was the same and I lost some HP....so....I'm going to keep it where it's at right now, I'll post the map if anyone wants to take a look, I cleaned it up some too.

mods:

Blouch Dominator 3.5 turbo
3 inch TBE
3 inch intake
K&N filter
MBC set to 30psi
SMC alky injection, starts spraying at 11psi, full spray at 17psi, 7gph nozzle
walbro fuel pump
hks 272/272 cams
PTE 880cc injectors


still lots of stock stuff on the car including intercooler.

I'm actually going to do some DLL testing on an ebay intercooler soon and see what happens.


For right now here is the before and after


the bench mark run is 21psi 93octane and alky, the after run is 30psi 93 octane and alky

Finished the map....cranked the boost a little bit....made a lot more torque (418) and almost 500hp (492)


I think once I upgrade the intercooler I can get up over the 500hp mark.

 

That fuel map just boggles my mind. What is the reason you are doing it like that? How come you aren't making your timing map the same? You really don't want to rescale the load columns either eh?

 

+1.

Like I said, I've actually done a rescale of the load ranges already, ( not hard is it?).

In that DLL screenie, does it mater that Atmos pressure is set to 75 kpa ( 10 psi)and Ambient Temp is 46 C if the SAE correction box is un-checked?

It would only matter if it were checked.

 

Why does the fuel map boggle the mind? Because there are parts of low load that would normally be under open loop? I tried to make it as smooth as possible, but I'd like to see what exactly makes you boggle.....

as far as rescaling, I couldnt find the how to =p I was getting around to it though =p
