Thermostat question

[GSLSE20B]

Thermostat is like an intercooler . You are not going to make more power , just keep the power you are already making a little longer . stability in temperature is the reason I changed to the reische .

U know what everybody stock go change your tstat and get all this hp these guys are talking about.lol.

can you quote the posts that are talking about "all this HP?"

A stock mustang also doesn't "need" any mods at all so everyone leave your cars bone stock!

We are in the Engine MODIFICATION section of a Mustang forum....this is not the Engine LEAVE IT STOCK section.

Leave your stock thermostat in your car and be happy.

Wow. You show some one the numbers. They understand the numbers and still deny there is a benefit. Mind blown.

Yea genius post #128 wont u read before u challange someone.

I know you said you have been doing this for 30 years. I'm assuming you are an old dude and have no computer programming knowledge. These ecus use a very complex code that had only been around a few years. If you understand it so well can you show me exactly how the ect correction adder gets disabled in certain conditions?Besides a tuner who zeros it all out.

Well if u consider 48 old thats me i diagnose computers everyday,im not a tuner,but i understand how moderen computers work very well.

So you have never even looked at how the ecu controls the variables of your engine and you are claiming your experience with cars tells you a lower thermostat doesn't help power. Did you know in the late 60s guys were removing them to increase timing through the distributor for increased HP? Your ecu does it for you now a days you just need to replace the tstat. You have 30 years of experience losing races.

Well lets see i ran 12.3 on stock tires with tune intake and cat deletes,at 116 mph with the stock tstat in.Now inhave axles and drag radials and be in the 11 s when the track opens,still with the stock tstat.I am however changing my soon because WITH MY MODS it will benefit me.

No shit were talking about a stock car gaining up to 16 hp by hanging a lower tsta.Its not happening..Now your talking about how much is to be gained tuned,which i already know.Were Talking ABOUT A STOCK CAR.

Cool your jets, this is a friendly discussion with people trying to provide valid and relevant information to justify this product. The factory mustang ECU, even with stock calibration, will add and retard timing based on many different factors. Octane, IAT, load, ECT, etc...

What Higgs and Mark are getting at, is there is a specific table that will advance and retard igntion advance based on engine coolant temperatures. Mark gave us a preview from his VCM editor displaying these tables. This is a factory table. Which means, a BONE STOCK car will advance timing based on ECTs. Did you know that the factory ignition advance tables actually have a fairly low borderline spark limit but the knock sensor will add timing as long as there is no knock present and based on all of the other conditions I previously mentioned. That being said, it is very likely that the .5-1.3* of ignition advance Mark previously mentioned is very possible for a BONE STOCK tune to advance timing with engine coolant temps dropping 10-15 degrees below the factory thermostat ECT target.

You may not know how to tune or much about these ECUs, but we do...

I was originally questionable about this particular modification as well, until I reviewed the facts and considered what the ECU is capable of.

I'm sorry I was being an asshole. Your quarter mile times have nothing to do with how a tstat lets an engine make more power. I don't know why you think only a slightly modified car will benefit from lower coolant temperatures, but a stock car won't. The adder table is very clear about it. That table is separate from the knock sensors. It just gets added in to the numerous other variables to become the final ignition timing. It is factored into every commanded spark by the ecu.

Yea genius post #128 wont u read before u challange someone.

better re-read the post. he didn't say a thermostat makes more power, he said that spark lead is added or subtracted based on ECT....and yes, 1-2 degrees of spark can have a significant effect on power.

"genius," lol.

edit: I got tree'd, above.

Being the asshole is your job. The forum should give you an exemption for the entertainment value.

Nice try!!!.Yes timing will add quite a bit of hp,however that wont happen on a stock car just by changing the tstat.Unless u drive in above 100 degree temps everyday doing wot pulls.Genius!!!!.

Let me ask u this,do u know a car can overheat by not having tstat in and the coolant being full.Since u know so m uch about thermal dynamics tell me how?And everything eles is in working condition.
