PR3 b16 ecu, Spoon cipped, Good deal??
 

As most of you know i ve been looking for an ecu , i found one , heres are the specs or what the guy told me, Oh he wants 175 for it.
"
It was chipped by Prospeed.

He said these are like the Spoon spec. But really it is just Type R fuel and ignition curves as this ecu was running a B18C5. It does not have extreme ignition or fuel tables. "


Is it worth it?

assuming this is what you are talking about:

JDM CRX 89-91 B16A (pr3)
Spoon Spec
VTEC: 4,500 rpm's
Redline: 8,500 rpm's Upgraded

My biggest complaint is that VTEC kicks in way to early with this program.

you won't be able to cruise at 140 because you'll always be touching VTEC

For your use you should find a computer that VTEC engages between 5200 and 5700 rpm

The price is on the goodside of decent, but because of where VTEC kicks in, I say move on.

try contacting www.hyperducktuning.com or ebay

Thanks for the quick reply.

I think the Spoon chip will also make your car run rich. I say stay away from that chip unless you're getting your motor built properly for that program.

yea hyper duck tuning (Adrian) makes any chip for any spec you want... another option is to get the stock pr3 ecu and get a vtec (Vafc or SFC) controller... which one you pick is up to you. both control vtec crossover point as well as fueling. But definitely check out adrian. He can at least give you some good advice.

forget a VAFC... no way. also stay away from chipped computers unless you wanna get 250-300 kms/tank of gas.

use a stock computer, OR use chipped SOHC computer for the ultimate cheap solution! check out pgmfi.org for chipping info or contact hyperduck as Sam mentioned.

laynlow13,

basically Bruno is saying stay away from a computer that is chipped with a generic performance chip....

if your going to chip chip to get the timing and fuel flow optimized for your car... this requires a dyno

Paul at Neetronic's can burn chips and has a dyno too.. he's definitly worth talking to as well.

I agree. If you have a stock motor or a motor with just a few bolt ons, the only thing a chip will do is guzzle gas and make your car run rich. Especially the Spoon and Mugen programs unless you build your motor to their specs. Not worth it in my opinion. But it's your car so do as you please. This is just a heads up.

what do the chips do really? do they add horsepower, i alwyas wondered about this ecu chipping what does it do exactly?

^^^ incase you can't tell just be reading this thread...it lets you reprogram where vtec kicks in...fuel mapping...etc.

The ECU controls things like VTEC, FUEL and timing

basically by tuning the ECU you are changing it's characteristics for the differences in the engine

I have a 2k sir with an obd1 chipped ecu and for all the money that can be spent on a car for some sort of performance upgrade, the cipped ecu was the best bang for the buck. I got four chips when I bought the ecu and i ended up with a 9700 rpm red line and the car burns less gas than before and it just runs better. The best part about it is if you dont like the chip just remove it and install a different one for like 50 bucks and try it. Really for all of the pointless stuff people spend their car money on that is very inexpensive. Just look for cams or valve springs if you buy those, you spent 2gs and have a minimal gain. Just my two cents...

I think it's all in the mind. I highly doubt you're burning less gas. If you are, your car might be running a little lean. Which chip are you using?
Also, running at 9700 rpm doesn't mean it's better. If you keep pushing it up to there, you're gonna stress the parts out too much.

I get alomst 70 more k per tank, have you ever diven a stock sir for a while, you get from 375 to 450 k per tank i have owned it since new and now i get around 500 to 550 k per tank, it is not lean, because the carbon build up on the exhaust is a little rich, rich is good, fuel is there to burn 9700 rpm is not always good, but I have heavy valve springs and top end cams and hi comp pistons in it. The cams are degreed for top end and I really dont care that in 50k time I will have to do another valve job, the car hauls ass. I red line the car all day long. All I was saying is for the 320 dollars I spent on the ecu, made more difference in drivability then the other things I did. It is all a piece of the puzzle though. If it didnt work, I would have chalked the 320 up to r and d and took it out.

Here's the difference. You chipped a car that has some internal mods. I think this thread is in regards to chipping a completely stock motor. Also, running rich is not a good thing. And, I think 500 kms on a full tank is what you should be getting on a stock SiR motor.
What chip are you using?

if you knew anything about ECUs, you wouldn't be :confused:

it should be clear to anyone with any background that a chipped ECU is one with a program other than stock... which means dumping a lot of fuel and advancing timing to make any power.

a SOHC ECU can be 'chipped' with the STOCK DOHC VTEC maps so it can run the swapped engine as if it were stock.... so stay away from non-stock maps in an ECU unless you have a wideband and a dyno

A 9700rpm redline is a perfect example of how silly "chips" can be and how uneducate "tuners" (I use the term loosely) can be. I have to assume that whom ever tuned/programmed this chip did not intend it to be used on a stock motor. Therefore, they have also not tuned the fuel and/or timing for a stock motor. I make this assumption because any "tuner" will know that there are not many cams out there that will make power north of 9k rpm...so to have a redline of 9700 is all but retarded.

Therefore, there is no way in hell it performs better than a factory tuned Honda ecu/motor combination.

Happy's $0.02

I am surprised at the last thread, I have no problem admitting when there is a bad decison made on my car or motorcycle I have had so many vehicles and none of which have been stock. I built the motor and it ran really well except for the low red line. The car does 215km per hour in fourth, thanx to the high red line, and how can you say that the car doesnt work better than stock. It would barly do 190km per hour with four people in it now will do easily over 210 that was in fourth gear no less. The 9700 rpm red line doesnt make the power though but does let the car go faster. It stops pulling around 9200 That I agree revs dont equal horsepower. I dont remember the name of the chip that is in there, I really didnt pay attention to it. I was not willing to spend the money to tune it properly with a dyno, I will do that in the future for sure but all I said was bang for the buck it gave me alot. And as for fuel consumption Where is this stock sir that gets 500 k to a tank, have you driven one? if so you would retract that statement, even when highway driven and barley on the gas will it break the 450k mark, in the city and on the gas it gets like 350 400k max. Not compaining but making a statement. For the 9k rpm power, the engine will make power that high with cam timing, anyone knows that, it may not make torque but sure will make horspower. Whatever the case the car is much stronger and faster than stock, I will never take it to a racetrack for a stupid quarter mile time I have nothing to prove.
