I'm really leaning towards Hondata for fuel management, but have worries about part throttle hesitation. I will be daily driving my car, and I usually take many highway trips at 65-70, and don't want to deal with hesitation. What do you guys think I should do? How many people have to deal with the Hondata hesitation and is it really that unbearable?

BTW...I will be running it on a P72.

 

really its not unbearable. its just annoying.

It only happens between a certain throttle percentage so if you are giving it a little more gas or a little less, it will not happen.

I have found two really good solutions, haven't tried them yet but others have had sucessful results.

On the dyno if they richen up columns 4-5 about 15% it should smooth out some.

Another is if you use a P28 base map and save the dyno'ed P72 settings over top, the hesitation seems to dissappear.

i will have to try this

there was a huge thread on this a while back, i would do a searh maybe some good info

 

I have tuned a few cars with p72 and p28 with the latest software and the problem seems to be eliminated, One particular car had the hesitation and after updating the rom image the problem is gone.

That's what I wanted to hear.

 

The hesitation is at 300kg/mm and it's annoying

im using 3.5.3 and it still has hesitations, ive tried everything u can imagine.

tried changing ignition values, tried converting roms, the only thing that works is to richen up those areas.

it happens on about 60-70% of the cars i see.

 

There is an extensive thread on the hondata board about this.
