I haven't looked at that section of the service manual for a while, so there "might" be (not sure on that, though). The ECU should be "self learning" and from what I can see just skimming over that section, there is an "inspection" you can do to check the idle condition of the car. Unfortunately, this inspection involves steps that would create another warning light on the dash that will need to be corrected. Therefore, I don't recommend doing this at home as it will create other conditions that you might not want to deal with.
In any case, the inspection will result in a possible further diagnosis of several other systems on the car. All in all, it is not a pleasant thing to have to chase down. The best thing to do is to hope that the ECU will be smart enough to figure it out after a few driving cycles. The key is in the driver knowing what NOT to do so as to not interfere with the ECU's processes.

As for the Optima batteries, there was a post here only a few days ago from a member who is actually an Optima distributor. He admitted that Optima has had a run of really bad batteries some time ago where many units were defective. This lent to his own frustration with the product as well as the bad reputation that has surrounded the brand. He also indicated that Optima has "apparently" resolved these issues, however, as a consumer, I don't find that very comforting and when faced with so many other very good, cheaper alternatives, I'm not willing to spend that kind of money on a product that may not perform to the standards of operation and time that their prices would dictate.

 

The spoon, t1r, etc are all the same as the oddyssey I believe. The company that manufactures them sells them and other companies rebadge them. You can find an oddyssey on ebay for around 60 bucks.

 

I thought the T1R is the same as oem for volts/ watts etc. but smaller and lighter while the others don't have the same wattage.

 

It depends on what you are looking for. Optima has a very good power/weight ratio, better than the Hawker/Odyssey. A Hawker with similar capacity to a group 51 Optima weighs 5 lbs more. I posted a thread about this somewhere here, but I'm too lazy to look it up now.

You save a lot of weight, but sacrifice CCA and reserve capacity.

 

Car batteries aren't rated in "watts" (that would be stereo components). Car batteries for modern day cars are all rated in 12 VDC and are rated in CCA (cold cranking amps). The stock one and aftermarket replacements for them are rated between 450 CCA and 550 CCA. Although the T1R battery is "advertised" as having more cranking amps than the OEM battery, nowhere have I seen it published. It is highly suspect that by nature of its shear physical size, that it will have more CCA than the OEM size of battery (and more importantly, to be able to sustain that amperage for a reasonable length of time).
I've used one of these little compact type of batteries (Hawker Genesis). It was in my S2000 till late fall came (less than 6 monts), at which time it got taken out (because it started to crank slower and slower as the temps got colder) and is still sitting at the side of my garage. You will be hard pressed to survive a real winter with one of these things nor will you be able to last long if you have a high output stereo system.
This T1R battery sells for $200.00 Cdn while I only paid around $75.00 Cdn for a well known bargain basement battery. Unless you absolutely must have weight reduction, a T1R makes no financial sense in any way, shape or form.

 

I live in San Diego. It doesn't get too cold here. I am more concerned about shaving some weight, then having a battery that produces a lot of CCA.

 

If you really like to reduce your car weight, there are some other things you may like to consisder:

Drain the windshield washer fluid and remove windshield wipers, because it is rarely rain in San Diego.
Take out spare tire and tools, replace them with fix-a-flat can.
Fill up your gas tank no more than half full.
Remove passenger seat, re-install would take less than 30 minutes if needed.

These things shave more than 50 pounds and cost almost nothing

Hawker Odyssey PC 680 works great, except when the weather gets below freezing. It's small and light, but only has 220 cca IIRC. It's only good for a few cranks when it's really cold before giving up entirely... I'm adding a second one to try to solve the problem.

But wouldn't that double your weight and double your cost? Doesn't this defeat the purpose of shaving weight?
