Hi Guys,just few questions that I want to ask..Not to ask but to compare data at your setups.
First I am having Starting problems with the car when she gets hot..she cranks bad,and the voltage falls to 9-10volts on cranking according to the AEM... and the cranking slow dose seem like a bad battery? but the battery is 8 months old and I have 2x1 farad caps on the car also for the ICE.I plan on checking Battery voltage directly on the battery when cranking also. when the Voltage is low the Cam crank sensor doesn

 

Get an Optima Yellow Top. I had issues with my OEM battery with all my audio/video stuff... It died after about 8 months. The capacitors would prevent this from happening once they got charged, but they suck a good bit of power on start-up to build up that charge... I have a single 1.5F capacitor myself...

I would think that the voltage would not drop that low... Do you have any issues with the dash lights dimming, stereo lights dimming, headlights dimming, etc? It is "better" or "worse" when cranking with the headlights on?

Do you have an automotive store that could test the battery for you? Just bring it in, they hook it up to a cart, and it tests the charge / discharge of the battery.

No problems during Stereo on IGN on,no dimming,no nothing but i forgot to add that when hot the static battery voltage before cranking when the car has IGN on is 11.4v or 11.6v
And cranks with 9-10v...
I had a yellow top specific for this car and the battery died 1 year and a month later,just died instantly...
and after that i had a cheap battery and it was for 1 year and i got an oversized Redtop For the car.I will make a pic of it..its a tight fit..almost touching the AC lines...

Stefce,

All appears pretty normal to me except the battery voltage. I have never logged my voltage but it seems counter intuitive that when the engine revs and higher rpm, spinning the alternator faster, that voltages would drop rather than go up. That being said, the voltages remain above 12v which means the alternator is doing it's job.

9k, why would the IAT temp tables affect his actual IAT's? Would they not only affect fueling (which doesn't appear to be an issue here)?
