1. That's with a very expensive Toda header. Noone knows what a reflash will do without one.
2. Sure the actual number "20" is significant, but you may find that in the real world, having that extra torque that close to the top end of the rev band is not where you want it. You want torque down low and HP up top.

In any case, this is diverging from what the OP wants to accomplish. He wants the "fun" to last longer, which in real terms, he wants each gear to last longer. Raising the redline will do this but at the expense of much higher piston speeds, something that Honda wanted to prevent. Longevity will suffer. I think I know what he wants. He just didn't know how to ask it.

 

Those gains are for the following mods:

Toda exhaust manifold
J's Racing straight pipe
Invidia exhaust
Hondata IMG
Hondata reflash

Hondata did not make a reflash on a bone-stock S2000. They used my S2000 to make the reflash, and when they first got it I had an Invidia exhaust on it.

 

1. No, we won't know unless Hondata decides to do more testing (and thus produce more reflashes). I highly doubt this will happen.
2. The 20ft-lb gain was at that specific data point (~5800). As you can see from the graph, there is a hefty increase from ~4200 (which just happens to be the VTEC engagement point) to 5800. The gain at 4200 is ~18ft-lbs. If we are hoping to gain more torque below 4200 it just isn't going to happen with bolt-ons. A supercharger won't give you the gains you want. You need a turbocharger to get big increases in low-end torque.

 

I don't think I'll argue the functionality of 20 lb/ft of torque in a place that may or may not be of any use to anyone. If you think it's worth several thousand dollars for 20 lb/ft, noone can argue this. Satisfaction with money spent is always in the wallet of the owner.

 

Well, from my point it is worth it because I didn't spend several thousand dollars.

Toda header: $950
Invidia exhaust: $650
AEM CAI: free
Hondata IMG: free
Hondata reflash: free

Total cost: $1600

$1600 for 20ft-lbs (at the wheels) on an S2000 isn't bad.

 

That's you. The rest of the mortal world would pay for all that stuff you got for free. And although we sometimes consider our own labor to put stuff on as being free, that's gotta count for something, especially those who must pay an hourly fee to have it done. IMO, the Hondata reflash is not cost effective in any way, shape or form.

 

I wonder why Hondata didn't dyno the car with all the mods minus the Hondata. I'm also curious how much more you could net by going with a single outlet exhaust.

 

Ok...let's put this in perspective. When you upgrade your OEM header to an aftermarket header you will need to tune the ECU to compensate for the differences (your AFR will be all jacked up). You can tune your ECU through one of the following:

1. AEM EMS - $1500
2. VAFC - $400
3. Hondata reflash - $595

If you have an AEM EMS or VAFC you (most people that is) will need to pay a professional tuner to tune your car. $150/hour is the going rate. Estimated time to properly tune the car is 2 hours. That is $300 towards tuning. So, if you have an AEM EMS you will have spent $1800 and for those with a VAFC $700.

Now, an AEM EMS or VAFC allows you to continuously tune the car whereas the Hondata reflash is a one time deal. Irregardless, I think it is flat out wrong to say that the Hondata reflash is not cost effective.

 

They did...the bottom line on the dyno graph I posted is without the reflash.
