Those ac recover values are certainly not correct..ie. the two values that are 9999rpm right now They are suppose to be around 1000rpm....Maybe some one with a 25det pfc would be able to give you the default values although i think this would not affect idle directly. Did they perform the idle learn proceedure on the pfc at installation?

Ok guys this is the info. i aquired and this is what i'm going to use after lots of research... Firstly you need to calculate the overall rim AND tyre diameter so using a 265/35/18 18" x 25.4 = 457.2mm 2(0.35 x 265) = 185.5mm Total dia.> 457.2+185.5= 642.7mm Next i want a toe of 2mm IN on either side so Deg= 2(mm) x [ 115 / 642.7] Deg= 0.357* for a toe in of 2mm per side Toe IN is a positive value and toe OUT is a negative value There are a couple of ways to calculate this but this method is the simpliest....well for me at least and i should note that you guys need to double check if your alignment shop reads toe in mm or degrees to make sure you are setting up your ride properly because it seems that all the newer machines measure in degrees and not mm.

Looks like plugs for abs unit The other two plugs by the air box will most likely be for the boost solenoid and the ac compressor? (if its a single wire) maybe u can though up a pic of those as well....wouldnt affect the running even though

Hey guys i need to get my wheels aligned but the shop has the adjustment for toe in degrees and not mm Any one know how to convert mm to degrees? I've read up on some stuff but still not sure as some suggest using just the rim diameter but others suggest using the overall tyre diameter....i run 18"gtr wheels 235/40/18 up front and 265/35/18 rear I plan on running 0* front and 2mm in on each side on the rear Any links to calculators or such will be appriciated Thanks

A quick way to know if it held the tune is you can go to settings>air flow> and see if VG30 is highlighted.....if so the tune is still there otherwise it would have defaulted to RB25

Nah.... The 3 lower lines ie. black, red, and light blue is hp with their matching colored torque lines as stated above.....so for reference from the graph at 3000rpm it makes about 10hp and 17 ft-lbs more when nvcs is activated

Green / black = stock ecu 10psi Dark blue / Red = Tuned ecu 10 psi nvcs on from 1500rpm right up ( notice how it shits itself after 5000rpm) Orange / Light Blue = Tuned ecu 10 psi nvcs off Its there... but i dont know if i'd refer to it as a "massive" difference

If its only when the soleniod is activated then is got to be somthing with the vct mechanism???

I used to have mine triggered by a msd digital window sw and tried numerous on/off switchin pts and the difference was verrrrry minimal with the seat of the pants meter....waste of time in my book ......this was on the stock ecu tho, it only decresed spool time by a couple 100rpm

Whats wrnog with your current engine? blown?

??? With my measly 260kw i felt a noticeable difference goin from std 33gtr box to apexi pods AND a big ass sealed box with a 3" and a 4" pvc pipe feeding from under the guard/bumper Pods are proven to flow more is just that you have to go thru the hassle of fabricating to seal and feed them properly as you probably already know.....but if youre going for a more or less legal look that idea is out the window

My bad but i havent used my hc since i got datalogit so i just realised that map tracer on the hc does not show a gradual movement from one cell to the other like datalogit does....it just jumps to the next cell so you would only see it in one cell at a time but bascially what i described before is what happens so hope you get the picture What Paul means by "locked" is that if you make any changes to the idle cell on the ign map the pfc will still hold timing at 20* by default, likewise you could turn your cas from now till tommorrow and the pfc will still show 20* at idle However if you use the temp ign/inj in settings to adjust the ign it holds whatever value you enter......wierd

Hell no Larger twins (-5) will just get you more lag and power you cant use because of an unbuilt bottom end For 400rwhp -7 or -9 is as good as it gets

I could be wrong but the rb26 pfc does not use timing to adjust the idle....well at least the Ljetro. I think this is only for MAP based pfc as it has the option to turn it off and on on under setting 1 ....I would think closed loop better describes afr because with closed loop switched on on the pfc while crusing the afr bounces back and forth to maintain stoich but the ignition timing reads a straight value of whatever cell it is using at the time Leeroy what cell/cells does it use at idle? I think whats happening is the the higher value youre seeing is the interpolated value....I'll try to explain.. The cell normally used at idle(on my car) is N1 P2 which shows on the 2nd map as 20* With the ac on it goes to N1 P3 which is also 20* @ 950-1000rpm. Now N1 by default is 800rpm and N2 is 1200rpm so 1200-800=400.......400/2=200.......200+800=1000 rpm ......so the pfc will use the value in N1 up to ABOUT 1000rpm, then it would start to use the interpolated value meaning, at around half way between the two cells it would calculate an average of the value in the cell its moving from to the cell its going to and use that value For instance from the 2nd map N1 P2= 20* and N2 P2= 22* so if you look at map tracer and the little box is about half way between these two cells which should be around 1000rpm the timing will be showing 21* Like wise when moving down the map with increased load or moving diagonal with increased load and rpm the same applies with interpolation So if your little black box is hovering around the center of these four cells..N1 P2, N1 P3, N2 P2, N2 P3 , it would be normal to see a value like 23* on the hc as it would be interpolating using values from all four cells I'm not sure about rb30s and the specs for timing but the 26 is 20* at crank from factory so i set it to that and tune from there because technically what ever you add to your base using the cas remember it would not be at idle alone but across the entire map The 1st map shown it the default datalogit map and the 2nd is the base pfc map Btw i'm not a professional tuner so this is just my 2c

??? Guess you figured out how to post now

Is this info in the owners manual??? I guess different testers would give different values but i would think what is more important like compression test, is the variance between individual cyls ?

^^^^^^ This is crucial and may make two identical setups making the same pwr look totally different when it comes to numbers on the ign map The 2nd map is the base pfc map for the 26 with a degree or two changed in some places and the first map looks pretty relaxed to me in the first 6 rows or so. With my cas set to 20* i added 4* to the first 8x10 cells (2nd Map) and the car feels a whole lot better in the transition into boost and has no noticeable increase in knock....the question is how much more can it take because im not even sure if the knk sensors will pick it up that low in the rev range The point is every car is different so is a matter of trial and error to see what works for you

Exactly It really is easy as the pfc has the base already set up but you must know the basics about tuning and engine parameters to start with I've had my datalogit only acouple weeks now and have already gotten the wot tune spot on even though i'm still learning little tips and tricks using the software and i am working on the low load/cruize now.....its a beeeze compared to using the hc And as said before pfc does not pull timing or anything like that when it senses det...but the most important thing is it does detect it !!! this is what sealed the deal for me Every Tom Dick and Harry has one here so you could get support if needed although some remained tight lipped probably because of fear that you might become the next best tuner but say what, lots or reading and trial and error will get you there

From the write up on the new celica forum linked from Pauls faq I was of the impression that basic knock reads higher and is used to trigger the engine light so i was using basic until i saw the engine light flicker and searched thru the log to see what cell was the culprit and didnt see any abnormal values....i did however find it in the advanced knock log so i guess the pfc uses advanced to trigger the engine light and well of course show the same value on the hc Is ther any reason why you guys pick which one you want log?...I have everything ticked just in case i might need it

Yeh i'm not concerned with wot tuning....thats piss easy Thanks for the idea of using the chart to log tho never thought about it...that will show exactly when youre pressing and the corresponding afr as oppesed to map watch that logs decel values and mess up the reading Only had datalogit for a couple wks now so still figuring out the tricks Just to confirm do you use advanced or basic knock?.....Its advanced knock that triggers the engine light right? Thanks

Just throwing this up to see what you guys think..... Im particularly interested in the top right hand side of the map...... and do you actually tune the decel row(x)?....The lean afrs on decel in that row screws with the log and makes it hard to tune and i find its hard to hold it on those cells on the road.......i guess thats what dynos are for Anyway this is my target map for a stock turboed 26 usual other mods...... 0psi = 2000rpm , 5psi =2500rpm , 10psi = 3500rpm The colored cells is a trace in 4th afr1.xlsx

For some reason i always thought tuning when the weather is hot was better in that due to the temps already being high you know the max timing that can be dialed in before it pings as the likely hood of it detonating is worse due to high temps and during the night yes it would run a little lean but the cool intake temps would hold down detonation ?

Is this a track or street car? What ron fuel you use?

The problem was i couldnt get to copy the file to use on another pc I figured out what i was doing wrong although it still seems strange to me When i opened the file i saved from datalogit and select it, i was trying to copy and paste and also drag and drop the file unto my flash and a window comes up telling me the file is no longer located in C> prgramme files> fc edit>maps and to verify the item location and try again ..... Its only when i select the file right click > send to it then copies it to the flash.....I though it should have worked any of the 3 ways So its back to tuning....... What do you guys use to view the following parameters ie. Basic or Advanced > Aux an1-an2 wide band - I use Avg Knock - I use Basic > Max And what to use as the map source?...... Advanced or Map Ref ? Thanks again guys
