ebay chipping

[Memphis]

do anyone know if those spoon or mugen ecu chips sold on ebay reliable?

[jhoff]

no
there a waste of money
all it does is tell your ecu/pcm that you are at wide open throttle all the time

[Lawman_745]

Definite waste man. My friend bought one for his civic and it was trash. Remember, you get what you pay for.

you know where i can get a reliable chip? my p13 is bad (its telling me the vtec solenoid is no good, but the solenloids works). so imma chip a p28

[lucid]

yeah go ahead and rip it to that 9k rev limit too, it might make it there once.
NOOOOOOO!
If you don't know someone...
http://www.moates.net/index.php?cPath=25_37 have the HONDA1 kit installed in your ECU by a TV/VCR/Electronics repair man to not get ripped off by tuners, and get tuned or buy a chip or converted ECU from these guys:

You'd be buying a $1 chip with some idiot's program on it from ebay.

edit: saw the above post after posting...don't chip a P13 btw.
Phearable is the easiest thing, under $200 shipped, plug and play.

Waste of $ as everyone has already said.
The "Chipped ECU's" found on e-bay usually just add a bit extra fuel and have slight modifications to the timing map.
I've even seen ones that have had nothing done to them, yet were being sold as chipped.

However, you failed to mention your application, The standard F22 ecu can't be chipped.
If you really want a chipped ecu, you need to get a chipped P28 or P06 and find someone to tune it specifically to your car to get the best results. Which would mean that you have significant engine mods to require tuning

[jhoff]

what about a piggy back? they are not the best for tuning but can be stable.

Why piggybacks (vafc, emanage) "suck" by pgmfi:
Piggy Back controllers allow stock ECUs to do things that they normally can't do, like run larger injectors or deal with boost. Remember that piggyback controllers work by altering sensor signals before they get to the ECU.
Most of the time, the primary signal being messed with is the Map Sensor. This is critically important in a Speed Density car. The Map Sensor is used by the ECU to guess how much air is going into the car, and therefore how much fuel to supply in order to match airflow. When you "lean" out a car with an AFC, you are simply decreasing the Map Sensor signal - the ECU responds to the decrease in manifold pressure by supplying less fuel. When you "richen" a car with an AFC, you are simply increasing the Map Sensor signal - the ECU responds to the increase in manifold pressure by supplying more fuel.
The change in fueling happens for a reason: if you look at a fuel table, Map Sensor values correspond with columns. When you increase or decrease the signal from the Map Sensor, you are simply making the ECU use a different column than it originally would have used. (see Understanding Maps if you need some help understanding reading Fuel and Ign tables)
But wait, isn't the Map Sensor used for determining ignition requirements too? When you "lean" out a car with a Piggy Back, you also in all likelyhood advanced timing. When you "richen" a car with a Piggy Back, you also in all likelyhood retarded timing. Look at trends horizontally (as MAP changes) in an ignition table, and you will see why this happens. This helps explain why so many boosted cars running on the "AFC hack" have issues due to excessive ignition advance.
The bottom line: Piggy Back Controllers suck because you cannot independently adjust fuel and ignition. Any changes to fueling will produce a change in ignition too, and often this is undesirable.

piggybacks have their place. they are older technology that still gets used... you can make power with a afc but on something like a stock f22 the changes will be minimal BUT even with a chipped ecu they arent that much better... on a motor worth getting tuned to make ideal power the afc will come in a far second behind a chipped ecu. but like i said they have their place. the afc hack. dsm guys and the such utilize the fuel controllers... i use mine to add fuel for my first stage of nitrous and control my gas mileage (even though im chipped) i lean it out a little to help. plus they can help with on the fly changes. like when i upped my shot and didnt have the computer with me. the afc save my ass so i could bump up my shot. and it controlled the first 75 shot dry i had. they do their job

For the price of a piggyback system, you can run a chipped ECU. You just need to take the time to learn how to chip and tune such a thing. Then again, you need to learn how to tune a piggyback system as well.

That's what I was thinking too. It's not like the pb system is any cheaper.
You don't even really need to tune to see good gains if you have a motor with stock internals since there are plenty of good (base)maps out there for those motors.
The chipped ECU can actually be cheaper if you are or have friends that are tune-savvy.

You'd need to get a good tuneable ECU like a P72 or P28, but other than that, you can get a complete chipping kit for $16.

You can barely get a good piggyback ride for that.

[deevergote]

For an F22A, you can get away with a P06. I could get them for $15 a pop.

Chipping takes soldering skill. Tuning takes some fairly expensive tools (a wideband o2 sensor is a must, as well as some tuning software, a computer to run the software, and a chip burner... other things can come in handy... vac gauge, egt sensor, etc...)

Tuning itself is a very involved process. Even the members here that are quite skilled are still learning. With an NA F22A, "good enough" will get you by. And yes, a generic tune won't hurt anything (won't be optimal, but it'll do for starters). Once you get into heavier NA mods or forced induction, THEN you had better know what you're doing! (and a basemap won't be good then)

i just would not trust anything controlling the inner workings of your car purchased on ebay. Its just like anything else... do it right the first time... It saves problems later.

[deevergote]

Purchasing quality parts on ebay is not a bad thing. Purchasing garbage on ebay is bad, however.

Has anybody heard of speed innovation??? There like phearable.net . speedinnovation.com ...check them out .

I would never buy anything like that onn ebay! thats somethine you need pro's to do!
