Why? The cat itself will free up 2 psi of potential boost making energy, the muffler is a dual chamber type with a spring loaded flapper valve the exhaust gas pushes on to open.
Maybe totally stock on 93oct might you be able to keep running in high octane maps with it

Just some good natured humour everyone - ha ha.
What, dont you think thats funny?

can someone else post what a good timing and fuel mape look like for a low mod ix.
I have not had anything in my car but 93-94 to date.
(this is why i am watching so much to see what people are running on the EVO's cause the hondas are much different)

WOT, the ECU will scan from both left to right/top to bottom and will transition at its own rate anyhow, could inputs such as that on (above) just be setting targets and allowing ECU to reach it at it's own rate? Or is this just wishful thinking for pasting timing values 50 blocks at a time.

We have seen the bad example now lets see a good one.

Blocks of same timing aren't always bad, and a smooth flowing map isn't always good..
Driving style, mods, intended purpose, etc.. all have a huge impact on what a tune looks like..
The more thorough a tune (hours or days) will be smoother in general than a dyno-day dyno tune, which in turn would look different than a mail-in flash..
What you should be asking is
"Given the current mods: <listed mods> what are the optimum timing and fuel values for the given range, and loads I will be using.."
You will very clearly see that at WOT people can easily rattle off a list of timing and AFR numbers.. But what if boost is raised or lowered.. The timing may not always remain the same, and fueling might be altered.. Also, part throttle load in open loop.. Well, you may still hit similar boost levels, but your AFR's would be altered and you'd have to adjust for that.
It takes time and tools to do it.. But it is actually fairly easy..
More complex settings also can affect the tune, and therefore it varies car to car..

I know you are not insinuating Jack that this could possibly be a good tune are you? I would hate to have to go against you.

Well I have a Cat back Junb.l is all. I guess when i tune my Honda I have more experience and I feel more comfortable before I go nuts on the EVO ECU I wanted to see a few sets of safe maps and try them out and see what I like and don't like for drivability. I guess what I am saying is that I don't have any experience tuning the EVO yet I have done FSAE racecars but that is a restricted motor. I have done my DSM but all I have there is a ram chargers box and I have done my Honda on both E-85 and pump gas this was done with Hondata.
So I am just trying to get up to speed on this car. (and learn from the experts)

I don't believe he said it was good or bad. just that a 'good tune' on the dyno will look different then a 'good tune' on the street which will look different then a 'good tune' at the track. I hope you understand this concept because I would hate to have to go against you.
