I got an anti-flood module from the guys at Performance Nexus it's stopped my hot-flooding problem completely! You beauty !
If you have the same problem you should go check it out. Their site is at www.rx7.d2g.com

So what that device is doing is most likely eliminating traces of voltage which is being stored in the caps of the ECU... This sounds like a joke to me. Why would people spend hundreds on new injectors and cleaning services?? They get the injectors cleaned and the leaking stops. Injectors are either opened or closed. No way the ecu is doing a half opened thing.

If you think this device will solve your flooding problems, first try unhooking your battery and see if thats stops flooding.

gee, I'm sorry.. I happen to have an aversion to trusting websites that use !!!!!!! everywhere..

Not too sure I trust a part when they won't tell you haw it works......."PLEASE DO NOT ASK FOR INFORMATION ON HOW THEY WORK ETC AS THIS INFORMATION
AND DESIGN IS PROPRIETARY AND WILL NOT BE DISCLOSED. THE INFORMATION ON THIS PAGE IS
THE ONLY INFORMATION THAT IS PUBLICLY AVAILABLE"............

But, if it actually worked for you then congrats

This device does nothing to the ECU, all it does is delay the fuel pump starting up slightly. It's a band-aid that removes one symptom, but does not fix the problem. The reason they say "don't ask how it works" is because this is about $5 worth of electronic components that could be assembled by any electronics amateur from a simple schematic.

I wouldn't be so quick to dismiss it. When I was living in Australia (back in 96), I had an 86 TII that had flooding problems, I took it to Ric Shaw Rotary in Sydney, and they installed some sort of chip/device (I'm guessing the same sort of thing), and I no longer had a flooding problem. When I spoke to Ric about the chip, he said that some guy in Texas used to make them, but he didn't know who.

It may not work for everyone, but if they are going to give a moneyback guarantee, you don't have much to lose.

Sometimes a bandaid solution is better than an $'X'000 solution. I've spent nearly CA$2000 trying to fix it, and I still have to use my kill switch. All this device would do is eliminate the kill switch, but it would still work.

Have you replaced the $1 transistor in the ECU that sometimes blows and causes this problem?

Care to elaborate?
Such as where is it, and a pic would be beautiful. I also made another post, so maybe that one would give you more info to what my car's doing. basically the same thing, but I think cranking the starter for a long time might be doing something to the trailing coil and making me think it's something else happening when it's really just flooding. sorry for that sentence, but you get the point.

This device is basically an automatic fuel pump switch. It's tapping into the Ignition +12v input to the ECU that sees when the car is cranking. It delays the signal a bit, so the ECU doesn't fire the injectors for a short period to circumvent flooding.

Mazda actually had a little doodad for dealers to install that was the same thing. It was a circuit board the size of a postage stamp that was covered in epoxy with the same 3-wire hookup.

I can't remember the guy in Texas's name who used to make the same deal - it was Mark something or the other. He had a good shop going, but had to close for financial concerns.

Anyhow, this is nothing but a fancy fuel pump switch. It's nice that it's automatic and works by itself, but you can accomplish the same thing with a $2 switch.

Fuel pump switch mearly works around the hot start/flooding issue.. it does NOT cure it.. .
In my opinion, the ECU can be partially blamed for the hot start problem just as much as dirty injectors..

The ECU does not compensate for a worn motor.... the initial crank fuel rate the ecu is set up is fine for a fresh motor, but begins to be a problem as a motor wears.. clean your injectors as much as you like, there is still a chance that you will have a hard time starting your car because too much fuel is being delivered during cranking..

I had a flooding/hotstart problem.. had all the injectors cleaned professionally.. checked everything over in the car (wasted countless of hours).. and still I was forced to use the fuel cut switch ... Ever since installing my wolf 3d and setting up my own fueling maps, I have had 0 occurance of flooding...
