Where were you for the Mazfest.

42 minutes of open track at the end of the day!

 

$1500 seems alot for 10 to 15 RWHP plus the head ache of tunning to get it.

 

Well.. All you really have to do is read my initial impressions thread and you'll know what my answer is. It's much much more than top end power.

 

think more long term. intake, exhaust, porting, turbo, maybe even nitrous.... you can tune around all of that stuff now. it's expensive for a stock n/a motor, but worth its weight in gold when you start the heavy mods. how many people are blowing up their engines when they reflash the computer with the greedy turbo and emangle?

just so you get an idea, if you pop an apex seal, you're about 99% guranteed you just toasted the rotor and housing. parts alone for that kind of rebuild are $2k+, not to mention the labor behind it. so 3500-4k for a rebuild if you pop it... the interceptor doesn't seem so expensive now, does it?

 

You're thinking in terms of peak horsepower. It gains everywhere at all load levels and it is quite nice. There really isn't a headache of tuning it. Just install it. It is far nicer than the stock maps as is.

 

It's called a torque shelf

 

the torque plateau?

 

Hey Scott.. Any idea when the graphs will be posted from the tuning session? Better yet, when will we receive the raw data files so that we can post up additional information?

Here is a link to the software that you can download from Dynojet in order to compare runs, show different information, etc... (I believe...)

Any further information on the fuel savings that can be had using the int-X? Has anyone leaned out the higher rpm (of course people have) but also a bit in the crusing rpm range as well? Can you do that?

Can you change when the secondary injectors come online?

 

Speaking of which, can you guys post your interceptor maps? I'm curious how they compare to each other, as well as the ones I posted after getting my car tuned by a local guy.

I'd like to know what (if any) difference there is between the turbo and n/a screens.

 

My car and John's got very similar results with the following differences in set up:

HKS exhaust on mine, B&B exhaust on John's
Smaller K&N intake filter on mine, Greddy intake on John's
I have UR underdrive pulleys with stock alternator pulley
I am running 17" and John is running 19"
We both have B&B test pipe.

Scott did John's car first and then use the same map on mine. After pulling some runs on dyno, mine afrs are very stable at around high 10 to low 11. Scott was consevative on timing since we have poor quality gas in Southern Cal. I will post my maps later this week.

They are two different cars before and after the tuning. Now the throttle response is instant, I got more gas mileage, as the decel function is on, which means no more fuel on overrun. Also I was albe to adjust the high speed crusing afr to around 15.

The car now drives like a oem turbo car. For people who are turbocharging their 8, get the Interceptor-X and more importantly, get it tuned right!

 

I remember one of the screen is disable on the turbo version and is replaced by screen 27, which will allow fuel enrichment based on rpm on the turbo version. Check your manual, it tells you which one is disabled (on the turbo version).

 

no one since there hasnt been a flash that affects fueling or timing since the greddy turbo kit was released

 

You are saying the "R" doesn't change fuel/ignition?

 

i dont remember it changing them. it was mainly for the heat issue- the high rpm while sitting still thing. i could be wrong of course but my point was that there hasnt been a flash since then so most people didnt install their greddy's and THEN get a flash that caused a blown engine.


edit ... hmmmm i seem to be mis remembering something. im going to have to go back and read some posts. i remember now there was an issue with the greddy maps being made based on M vs what the cars had.

 

^^ Exactly. The Greddy kit was set up on the "M" flash. Many people bought it way before "R" was available.
Then, Mazda issued "R" which actually caused an ignition signal incompatibility with the RPM dongle. They also pulled fuel and timing from the mid range and added fuel at idle. Some Greddy-ized people lost functionality altogether, some just got rough running. Others, oddly enough, saw no change at all.

I am still on "M" and will stay there until I see some compelling reason to have it flashed.

 

I think you just like the letter "M"

Any dyno graphs yet?

 

Don't you?


No new ones. Really, I don't care about that crap. All that matters to me is drivability and real-world acceleration. All this nonsense about "hitting the 300 mark" and such is starting to make me ill.
I had a 300 HP MX-3 it was pretty much undrivable. My 260 HP Miata was much faster. Thats right - faster. Even in a straight line.
My RX-8 is faster than just about everything I meet on a daily basis and it is nice to drive. That is all that matters to me and the HP rating won't reflect that no matter how high or low it is.

 

dynos are most excellent to disprove psycho somatic upgrades, though

 

Dynos yet?

 

True. And they are effective tuning tools.
However, showing a peak point is useless.

 

Like MazdaManiac said, What good is 300whp if you don't know how to use it!

Please take your car to the track (not the drag strip) and see what it can do. I think you will be suprised! A very nice trackable car.

 

i concur

 

I'll call up Scott tomorrow and ask him when we will receive the dyno charts. Maybe he can just give me the base files and I can post them up for him.
