thats good to hear...hopefully the new version with 3 bar support is coming out soon, i'd like to try it.

 

okay, I got a usdm stock p30 map and transfered the timing and fuel settings into a jdm p72 bin with knock disabled - would someone like to double check it before I go ahead and run it?

I have no place to host it but I will email it to whoever wants it or can host it - as long as someone double checks it first.

I am more worried about the timing, as I have a wideband that I will hook up and make some passes with.

I am kind of worried about the p30 ermbaseline.

EDIT: I want to make sure the timing is correct because I will spray niitrous on the engine soon. (I don't have my turbo yet - I will use uberdata to pull timing in the upper vac area for nitrous)</TD></TR></TABLE>

just pull timing in the upper area if you are worried. worst case you lose a few hp... but who cares as long as your motor lasts.

Well I was over 10.65 or whatever the exact number the stock quits at. The main part of making a 3 bar work when designing a rom editor is not just making it work above 1 bar of boost, its making it work right altogether since the ouput votage is totally different and needs to rescaled for the whole fuel map. Since it works right in vaccum and the boost levels im at now, odds are the small portion of the fuel map that I have not ventured into yet will be fine as well. In any event ill know within the next week after the fuel pump is swapped and the boost gets turned up even higher. Ill try and post dyno results after I go to the dyno as well.

The P30 maps are inferred over from USDM code. From what I remember, there was less fuel in the P30 than P72 .bin, although it was actually close near WOT. The ignition was similar but not identical... ~42 degrees advance in midrange part throttle is what you should have for either P72 or P30 maps.

I was comparing the p30ermbasline with the one I made, and the p30erm baseline is richer but timing is pretty close.

Anyway, I think I will use the b18c4 map and pull timing in the upper end like you suggested. Unless someone cares to look at my jdmp72withp30maps bin.

 

I compared the jdm p72 map with p30 values I made to the stock jdm p72. The one I made has timing advanced more than the p72. Hmm, wish I knew more about this

How the IABs are actuated is an OBD specific thing, not market origin thing, or so I thought.</TD></TR></TABLE>

USDM OBD2 == positive trigger

another question: when using the FTL, is the ecu just cutting the injectors? isn't this going to lead to detonation?

Running lean doesn't cause detonation, the heat in the chambers causes detonation. Running lean causes the temps to rise drastically, to the point where preignition occurs... with no fuel in the chambers, you can't possibly detonate.

IMO and AFAIK of course

 

so do people think this is safe? also, if you retard and dump fuel for your FTL, won't this kinda screw up your power band at that area when just driving around?

these guys dont think its a great idea

P30 stock runs more ignition advance then a P72 does stock. P72 runs more fuel then a P30 does stock. I can be more detailed if any buddy cares.

I don't think it's a great idea either I think it's more intended for drag-only cars.

 

FOR slashDEVslashNULL.
The reason for the P30 been more rich is that the fuel presure on the b16 is 43psi and for P72 b18c is 52psi

Ah, that makes sense. <FONT SIZE="2"><FONT COLOR="red"> But here is what I just noticed, the stock p30 is leaner than the jdm p72 BUT the p30 erm baseline is richer than both</FONT></FONT>

I have another question - I used crome to copy and paste from a stock usdmp30 to a jdm p72, some of the rpm points didn't exactly match up, like at 5773 I put values from 6019 and so on, will this be okay?

If you're using Crome, why don't you copy the USDM P30 maps to a JDM P30 bin? This way all the rpm and map points match up and you can add boost straight to the JDM P30 map with Crome. But only problem is you can't edit it with Uberdata afterwards.

Yeah I could do that in theory....in theory communism works........in theory.............

Seriously though, I know, I just want to use uberdata. (I'll keep my opinions to myself) I only used crome because I didn't want to manually edit the bins. Do you know if the jdm p30 has baro and injector test disabled - I guess it doesn't matter because I could use a edm p30 map.

 

In CROME you can change the RPM and MAP scalars to a match or a close one.

hmm maybe I'll go play with it

 

when running uberdata, are you in open loop all the time?

 

Fuel cut isn't as dangerous as some people think. Road Race Engineering has an excellent write up on the subject, as well as a traction control unit that operates off of just such a principle.

It is capable of working, but it's implementation is buggy. It's consistent, but there is a flaw in the UI.
Figure it out.

In tool box, open points adjustment, change col and row one at a time and hit close and the scalars are going to change.
DONT TOUCH THE FIRST AND LAST OF COL AND ROW IF YOU WANT YOUR CAR TO RUN.
