Gotta agree Robo!

I tried about 4 MT8s after my head upgrade, ended up on the equivalent to the MT7 I was using before.

After a fuckload of vtuning various maps........I came to the conclusion that you are best off trying each suitable base map first and comparing them all..........take your time............do the camdata run...........dial in your IVO for each.........(guesstimate your IVC!).............Don't even start to vtune until you are sure that you have the best of the available base maps to start with!

This will save you a HEAP of time and heartache!!!!!!

You may well find that the CAE is still the best one to go with..............but you can't be sure till you try the rest!!

Good luck with it!

One thing I look for with base maps, after I do the cam data recording, is were the MAP is during idle. Mid 30's is my ideal kpa at idle. I have found that the estimator is a good start but usually different from acual recording. That CAE is a good start.

Because that is where they usually idle stock and is the norm, but..... On MAP based AFR or Lambda you can still Vtune your idle. Idle is the start of all cruising and accel. Anything below 30 would be for decel. I really don't care how low it goes for decel. But this leave all the 30,40,45,50,55..... on up for adjustment. Basicly 13 columns to fine tune all other running conditions. If you are idling at say 50. That only leaves you 10 columns for fine adjustment. Get where i'm going? This works the same on all load based tables. Spark, spark temp correction..... Not that it will always be mid 30's... Got to follow what the cam data tells you. No matter with what base cal you try.

I haven't seen IVC affect kpa. My guess would be that sampling needs to be done in the middle or toward the beginning of the event. Medium rare?? Usually kpa at idle tends to be mid 30's to lower 40's. Gotta tune what is there.

With what I have seen. IVO & IVC affect MAP sampling but injector timing is the main point. Looking at airflow. Injecting 55 psi into a chamber is going to raise kpa. I have had a problem with pin pointing when kpa is sampled.

Maybe Steve will chime in.

That's a hell of a variation between the 2 sensors. 240Mv on the front seems way lean. The rear isn't to bad as you are on Decel and enleanment is cutting in.

Not really sure what you are trying to see by looking at the data screen. If you want to tune it in for your bike just use Vtune and let it do it's thing. One needs to understand that the data from the ECM is coming out at about 4 frames per second so you are only seeing about 25% of what is really there. So you need to see what you cannot if you want to make sense of it all. Vtune takes the data sorts it, tosses away the bad data then builds it back into a VE table just like what's in the ECM. That what takes time to understand and make work properly and we have a pretty good handle on that. There are a few who have tried to copy what we've done but there success rate hasn't been very good, as you need to understand what your missing before you can figure out how to rebuild it back in. If you want to learn some do a search on the net for under sampled data and there will be miles of data for you to read if you like.

Switching sensor which your bike has are design to switch the voltage up and down. This is how it is supposed to work.

so with tts how do you record your runs ?

using a laptop and interface setup to the bike.
