Here is the deal. When light cruising ive noticed my vehicle tends to drop rpms a bit and it almost feels like a misfire. Ive done a datalog and notice some really strange things going on that i cant explain but i would really like someone to take a look at it. A quick synopsis is that it seems like i lose alot of vacuum and the car thows a bunch of knock retard into the motor. Sometimes my AFRs will jump up really lean and sometimes they dont. I am attaching a few datalogs and my current tune. Any help is greatly appreciated. Thank you.
Mods list:
Full race 3"
custom 3.5" intake
invidia race header
rrc manifold
410cc injectors

Re: Need some help ASAP - Light load issue
I am not a tuner but I have not blown my engine :)
You need to add fuel to your tune.
0 Degree Low cam angle load lines 3 and 4 Add 15% fuel from 2500rpm down to redline
15 Degree Low cam angle load line 3 and 4 Add 15% fuel from 2500rpm down to redline
See if that resolves your issue

Re: Need some help ASAP - Light load issue
I recently tuned a customer's car and had experinced this.. he's also my best friend and everytime i've gone over, the problem hardly replicates itself.
The very first time this happened, i found alot of the cam angles really weird from a stock rom dump that i used from hondata as a base start. Once i cleaned up the angles, it got alot better.. but still does it to a point.
I've logged this car till i'm blue in the face, AFR is fine, angles are all evenly done and the ign is fine..Car is STUPID fast for what it is..
Just a AEM intake, Skunk2 alpha header and 3'' skunk2 exhaust. Car is running CONSISTANCE
14.1@100.01 mph on stock 17'' street tires/rims. These runs were on a hot night, and we hot lapped it over 19 times, and it ran very close times back to back everytime. I'd like to see if hondata can maybe chime in on this? I've added fuel it makes no difference..
