Hi Guys,

CA18DET EDM head and JDM block
CP pistons
GT2860RS a/r 0.86 (disco patato)
Approx. 700-800cc injectors
Z32 AFM
3"with 2" end muffler (law)
...350Z gearbox

1,4 Bar = 20 PSI

it ran 335bhp and 410Nm
Runs pretty rich 10-11:1

if anyone has tips on this map let me know!

Wow, those S13 maps are indeed anti-detonation tuned, interesting 8) Seems to look like it, can't come near the numbers of the s14a.. Instant detonation Maybe interesting; Comparison of the s15 sr20det; AT vs MT http://i12.photobucket.com/albums/a212/Freek_amersfoort/S15%20AT%20vs%20S15%20MT_zps9soy...

Hahaha exactly! so how can it have 250bhp?
There has to be a reason behind it, will ask F-Steve when he's in the Netherlands as hes a bit of a "Pete" around here

Hahaha damn... was hoping to get a better answer from the Nistune community
(just trying to understand before changing)

Perhaps someone has any idea of why they did this?!

But why does it have 10 deg more timing up top?
I also see this in other S15 ecu base maps, all the same engine right?? so should be able to safely run those stock maps

This looks like some s15 's have 20% more hp than others..

I understand, i meant that the last load-column on the S15 is "104" and on the S14 it's "134"

but wouldn't you expect the S14 to have more kW when looking at the timing figures?

Later(??) models of the S15 had the more aggressive timing, why would they drop that much timing?? 12deg up top ! :shock: Would love to hear peoples theory on this 8) Strange that they do report the same kW and Torque figures, and that the s14 is supposed to have less power than the S15 when clearly...

He all,

I just compared the base image of a S14A and a S15 (FP) and there is a crazy difference in timing, i thought they were the same engine type?!
Could anyone explain this?

Ok, thanks for looking at my tune! Do you have Pete's email for me? can 't seem to find it any where It pulls really lineair and is damn quick :mrgreen: I have build these det-cans; http://www.enginebasics.com/EFI%20Tuning/Det%20Cans.html just can't find a good spot to mount it, will try and email P...

He Matt (or Pete), Could you have a quick look at my current tune? Maxing out the 480cc's and stock AFM at 16-18 psi AFR: 11.0-11.5 Haven't found a good spot for mounting my old school det-cans, any tips for on the SR20? I think this should be pretty safe on a stock s15, any(!!) input is appreciated...

Have been reading a lot but something is not quite clear; If I raise the boost, and go above the original max load of 104, I go outside the map.. Raise the K to lower the load but that means my hole map should move a little too the left?? So at lower TP values there should be less timing and more fu...

He Matt, Everything is looking good so far, your fuel & ignition maps are looking really nice and consistent ! (can't say that from the stock Nissan tune, but I guess they had their reasons for it) Do you think i can put your ignition map in my ecu, check for knock and go from there? maybe put -...

Aaaah sweet, sweet corn !

To bad we don't have that here in the big NL...
your maps have way more timing than my stock maps and much less fuel.. would except a little less difference (looks like 20% diff)

Awesome Matt, thank you very much!
That's on ron ....98?

I thought that would be the reason..
So if I don't use the flex fuel maps there is still no reason to not run the Feature pack?
A "Better-in-every-way" update?!
