I used the above tune on track today and it was marvelous.

Thanks for all the tips PL.

One thing I did notice was post stint, I was running quite rich while driving around at walking speed. I assume it was my wideband unit playing up though due to the heat.

i did a graph for my mates s14a and it came out 280bhp 270lbft, put it on the dyno and it got the same results i'd say if you adjust the wheel size, find out the true weight of the car and double check your gear ratios are right then it'll be pretty close when you do your runs you need to be rollin...

I would be interested to see how close this figure actually is. I was getting 167 kw in the day from previous runs. Then I fixed up my tune according to PLs long wall of text and am now getting this figure 189kw which seems awefully high for my car. (t25 turbo at 9 psi sr20det). Now I really want to...

When I do my datalog runs. The estimated power graph does not mention my speed at the bottom (even through speed is in the logs and shown on the main graph). Also my power figures seem pretty damn high. what am I doing wrong? Pics: http://img143.imageshack.us/img143/372/3rd1.jpg http://img3.imagesha...

Ahh I see what im doing wrong. My load scalers are wrong, so im never hitting those cells... I have changed those scalers and also threw in some extra timing, corrected top end fuel map. New bin and logs inc. EDIT: That work SOO much better. I just ran a log previous and now through dataloglab and a...

Ill post a few logs now: Most of them are just me driving up 2nd and 3rd gear. Im running standard injectors and afm. I accidentally set a whole lot of values heals lean last night and it started detonating. My Wideband does not log to nistune unfortunately. However I know what you mean, however whe...

So far im hearing no detonation apart from the times where i have really stuffed up my fuel table. (kind of like a ta, ta.... ta .... ta ta.... ta sound right?) This is my fuel table which for more or less seems to give correct AFRs. Tested in 1st, 2nd, 3rd and half of 4th gear. I think Ill try thro...

I mainly want a safe-ish car that wont splode thus am only running 9 psi and want to keep it that way. The only issue im having at the moment is some bad performance when downshifting from high revs 3rd into 2ng gear, however my fuel table is still a mess, I played with it last night and am going to...

I have not turned up the boost yet. I'm not running expensive aftermarket cooling gear (bigger intercooler but thats it) and the car is mainly a track car so i don't want to boost it too much. (also im just running one of those bleed things, if you go crazy turning boost up on those things they spik...

I enjoyed your post!!! (bookmarked it even) I found the trail function after a few days of using nistune and has been a real help in tuning. You say 11.6-11.8 afr on full boost? At the moment my afrs are (although my fuel map still is not perfect): 14.7 low revs/no boost 12.4-12.8 during buildup 10....

Today we did one SR20det swap in AE86 gt28RS A/R64 nismo 555 Z32 AFM tubular manifold and FMIC but we did have some problem with OEM downpipe and no oil cooler so car did start overheating (and only one fan from AE 86 :) ) and we didn't make complete mapping but we did safe fuel map (10,9 AFR @ WOT...

S13 SR20DET IGN 16psi.jpg PL You use this as a starting point for S13s??? My timing table looks nothing like that. Im new to this all but isnt that quite aggressive? Im running stock turbo in my s13 still at 9psi. But the namestamp of that image suggests 16psi? I thought you retard the timings for ...

How do i upload nistune logs to dataloglab?

Is there a guide somewhere???

I see a few guys on here using the program which looks pretty good.

Fair enough,

I assume the ecu still detects knocks and jumps to the knock maps though (It appears it does from the logs).

How long after knock occurs will the engine start using the base map again? Eg 1 second after or is it so many rpm? or until the knock signal dissipates?
