Lund tune dyno result. On the money, or should it be making more?

Dakota @ Lund replied in <20mins to my request.

Added a degree of timing low down and switched the fans off.

Bloody love how easy it is with LUND and the NGauge.

New tune on the car within 40mins of sending the request. Awesome.

Are you saying they showed you a canned tune making 470HP? Or are you saying they showed you more power down low on the canned tune?

If the latter is the case, this is true, the canned SCT/DS/Ford/JDM run a lot of spark timing down low, typically 29 degrees between 2000-3500rpm, this is how they achieve the 40lb/ft gains.

Many of the professional tuners here will tell you that running such high spark down low, is not recommended, its how rods get bent, not saying the canned tunes are dangerous but the custom tuners tend to be around 24-27 degrees in the same area for safety unless your running very high octane or E85. The custom tunes come into play at higher RPM as the build timing with RPM, so the Lund tune should have more up top. :)
We don't run high timing at all, we are on the conservative side with timing always

I'm running your tune right now, at low RPM it makes quite high timing, not dangerous (no knock) but high like SCT and Ford canned maps do to get the 40lb/ft torque boost under 3000rpm.

My tune often sees 29 degrees at low RPM, maybe helped by good fuel I use here (RON99) and it then tapers of to 26-27 degrees at RPM builds.

Hit W rather than B. Brain fart.

It's crank HP.

SCT canned tunes are definetely stronger down low as they run a lot more timing, like I say I am running JDM tune which is based of the SCT and it can see 29 degrees as low as 2000rpm which holds to about 3500rpm, then it drops to 24-27 degrees to limiter. Whereas Lund build it slower (safer) to a peak of 29 degrees at limter, hence why more peak power.

Email Lund, show them a 3rd gear pull 1500-7000rpm and ask them if they can improve low-down power/torque at all or add in more timing. :)
I'm seeing 40-ish down low and it keeps 30 all the way up to 8100 rpm.
You will not gain any more power with more than 30 degrees of timing - even 100 octane race fuel will not help you.
I found that car makes the same power with good quality RON 95 so you really don't need to use RON 98 or RON 100.

You can trust Shell 95 all day long - it will not knock. I tried few different 98 form BP, Aral, Agip you name it and I had intermittent knock with few of them :crazy:

I'm always using Shell v-power RON 100 fuel for dyno and road pulls - never let me down.

I doubt at WOT your seeing 40, thats engine breaking time, maybe you mean partial throttle down low?

Down low at WOT for a moment - of course it will go down to 30 right away.
So not 40 then, just transition from partial to WOT, gonna say the engine would explode, cannot even run much beyond 32 at WOT even with E85 or race gas in the tank. I am not a tuner but I know any engine running 40 degree spark at WOT will result in bent rods, guaranteed.

Misunderstanding, right?

You can - I'm seeing 32-33 in my friend's tune on regular gas. You can advance far more on E85.

The thing is you will not make any more power above 30 with pump gas.

And again, 2015 Coyote "can" make it's peak power with RON 95 only, race gas will not change anything.

Mmmmm, really?
Need maybe a tuner or some of the US guys with E85 to chime in as to my knowledge those running E85 see around 32 peak at WOT, admittedly pretty much across entire rev range, would love to see an E85 from log to see what WOT timing the guys are making.

Agreed on pump gas, why nearly all the custom tuners like Lund, AED, Palm Beach all target for 29 degrees.

I've been running on E85 in the past - it's available in DE...

I will send you my logs next time you ask me to review your logs m8...will send you one with 33@WOT on regular gas...

Really interesting. There in no E85 here in the UK. :(

Gutted, Morrison supermarket use to sell it at their stations several years ago but pulled it.

Best we can get is RON99 (Vpower).

Yeah if you get chance, please send me a log from yours in 3rd from 1500-8000rpm would love to see. :)

Here you go - some screens. I need to check my "TUNING notebook" - I've had a log with 32.9 of "saftot" but this one is not that bad either.

First pic MT, GT350 mani. Second pic AT, GT350 mani, long tubes, S3 comp cams.

Right lower corner - peak values.
