Cool Aid Put on Hold

[Jack B]

I have been watching my 9L very closely looking for any type of pinging. I did encounter some over the weekend, the 9L is a worse case scenario with a higher compression ratio and higher cylinder pressure. What affects the 9L should not impact a stock engine. However, at this time we have to recall all those that were sold. Please contact Doug or Mark for a refund. I apologize, but, It is far better to error on the safe side. Please remove your Cool-Aid and send them back to your supplier.

Wow.... I was excited to try this in the future on my GenIV. Do you have any plans to continue to a finished product?

[Space Truckin]

Thanks for the update....

[BJG32]

Thanks Jack. Sorry to hear this...

A very stand up move Jack! What were the ambient temps in your city when you encountered the pinging?

The car was really heat soaked when i went wot.

[Jet Slicker]

Damn! I was really looking forward to getting one of these. Here's to hoping you can achieve a perfect product!

Let's talk other ideas. Has anyone tried filling a DSE heat shield with dry ice for 1/4 attempts?

What about scavenging air conditioned air to that area?

As Arizona said, very stand up move. What octane fuel were you using when you got the pinging?

93, it was just right, a guard rail on one side and traffic on the other, otherwise I would not have heard it.

hehe, I've thought about this for track sessions....

The computer pulls timing based on what it sees as IAT at the IAT sensor. IMHO, a problem occurs when the IAT is not accurate due to heat-soaking of the IAT sensor from sources other than actual inlet air temperature (sources such as engine bay heat affecting the MAFs with integral IAT sensors). If the IAT is ACTUALLY high, the computer SHOULD pull timing to protect from detonation, but if it is a false high reading, the computer will pull power and reduce performance when it is not needed. Cool-Aid was a good idea but it reduced the IAT readings in a linear fashion, regardless of the degree of heat-soak of the sensors. The situation is more complex and what is needed is a processor that compares actual IAT (taken in the airstream ahead of the MAF) with the reading taken from the IAT sensor and resolves the difference before a signal is sent to the PCM. A sophisticated processor could even be tuned to make adjustments for different fuel octanes or other performance adders that could affect detonation. I am looking at routing free airstream air over and around the MAF/IAT sensors (much like I do for MSD ignition boxes) to help control the engine bay heat-soak, but I don't expect a lot of improvement.

Why not just make it so that the harness drops the reading by ~20*? That would effectively represent ambient air temps for anyone with a DSE Heatshield or insulating wrap...

[Mclarengts]

Are the intake tubes getting so hot and heat soaked from the radiator fans blowing heat up on them?

[Viper.954]

Jack B, I've been following your threads on IAT. It's so hot in South Florida that I was afraid the 70 degree "IAT trick" would still be too cool, so I never bought one. You've spent your time and money on this project. I hope you figure it out. My Boss 302 also shows IAT. Once the car is underway, the IAT is with 1 degree of the outside temperature. Perhaps talking to a Ford IAT Guru would help. The mustang draws air from the fender well. Maybe it's a relocation of the sensor that's needed.

it is a long winter

[98intrigue]

Jack,
Your winter should be coming to an end soon. Any interest in being the coo laid back to life?

Winter is not over in NE Ohio. I think spring starts on Friday. It has been a brutal five months. I did finish my car projects (ARH, reflash, fuel pump, new wrap, glue sill insulation, new 5th gear) and will dyno this month. That puts coolaid behind fun things.

[Topplayer]

I look forward to getting my hands on one!

Don't tracks usually frown on liquid dripping out the bottom of the car when you are staging?

[blingnoring]

probably a stupid question, what is 'cool aid'?

You could always plug the drain holes. Would be worth a test at least and simple to do. You could then remove the drain plug from the airbox so it sucks in the cool air.

It is a drink resulting from mixing a sweet and flavored powder with water. It is also a device that Jack came up with to adjust the output from the Intake Air Sensors so the PCM reads them as cooler. The IAT sensors can heat soak causing the temps of incoming air to seem higher than it actually is.

lol. Thanks ViperGeorge. I just got a little concerned cause once my warranty runs out, I will be looking to do the 9L.
