ecu spoon on 99specR

[swapb18c]

ok my question is ...i will buy a p73 spoon ecu and i want to know if i will have some problem, because my friend said it will drive to rich for stock itr block?

just telle me the advantage and inconvenient of spoon ecu ? thank to reply me because i will taking the ecu this friday

 

[jugbugz]

huh? that doesn't make sense.

It only runs rich or lean depending on your fuel grade and climate conditions when you use a Tuned JDM ecu for Japan climate and fuel grade in your country.

I think JDM ecus run minimum 98octane - 100octane, so if you have less, you might run lean. vice versa

hmm, theres no such thing as 99specR. Theres only 96spec or 98spec. Is your ITR JDM or USDM?

 

[swapb18c]

sory because the guy who sell me the block said it's 99 jdm motor but you have reason it's a 98spec because is year of fabrication is 98/05/18

and for the octane in canada this is 87-91 and we have petro canada who have 94 octane... but i run it since 2 year's with 91-94 and for the climate winter can go to -30c and summer we have 30c(this year should be the last winter i will ran my civic). If i understand what you say i need to put octane booster if i run the spoon ecu to be not lean ?

thank to reply me, we learn every day

 

[jugbugz]

wow -30c?? Can you still drive???? Man I'd love to try driving with -30c AIR!!!! Should get massive torque and power gains... LOL

hmm, as long as the air is cold you don't have to run as high octane, but yes, during summer you'll need higher octane to avoid running lean and detonation.

If It's a JDM motor, then the ECU would match well but just keep an eye on the fuel you use and you should be fine.

Your engine won't be at maximum power because of your fuel. You should get a lot more power if you use 98-100octane.

For the spoon ecu tell me at wich RPM was the vtec and if i will see more performance. When spoon programme there ecu they have many programe or only one, because it's a use ecu and i want to know if it's possible to know the reel programe inside. ex: all spoon block
only camshaft spoon in itr
b16b stroked 1.8L

the only thing i know it's a p73 whit sticker spoon on it and its rectangle ecu not a square

 

[swapb18c]

i try the ecu today and the vtec start at 5200rpm and it will cut at 9000k but i finally decide to go whit a obd1 convertion. I buy a p08 with chip for itr and i will doing the convertion this summer with a good tune

Nice, i think vtec at 5200 is just too low

you don't really feel the vtec at this rpm

 

[MFactory]

If you feel the vtec when it changes over, then you're car is not as quick as it can be

In case you didn't know, the "vtec kick" is one of Honda's many marketing strategies.

for sure you going more fast when the vtec kick at 5k but if the vtec was kick like at 6k rpm i think it will be more fun and more agressive

it really depends...

SPOON ecu on B16A and B16B are well known to have a huge power dip between 5000rpm - 6000rpm. the High lobe doesn't work very well below 6000rpm for the 1.6L. VE aint good at that RPM.

The Power DIP is something that you can HEAR and FEEL on the road and evident on a DYNO. I've got SPOON ecu for my B16B and it's no good compared to others for STREET DRIVING. The top end is fine as thats what it was tuned for. Power Punches really hard when you hit 6000rpm.

I'm waiting on a SPOON ECU for my DC2R. It's a 98spec that I got off yahoo auctions Japan.

I'll confirm how it goes with the B18C.

I have a spoon ECU in the DC2 and is very good.
Vtec engages at 5000rpm and the engine performance is powerfull in all the rpm range.
Higher top end

I want one for my EG6 too, is expensive but work just perfect...

Well thats nice to hear. Because for the 1.6 engines, they don't work very well between 5000-6000rpm. Dynos show massive power dips here done in 4th gear... A friend has the same experience as me with his B16A. I currently also have that problem with the J's Racing ECU except it's only dipping between 5500-5800rpm. After this range, it betters the stock ecu from 6000rpm till 9100rpm.

The high lobe cam only works well from 6000rpm, below that, it's loosing power compared to the low cam. And the low cams still make power after 6000rpm, this is what I noticed when I REV it to 8000rpm when engine is cold...because Vtec is disabled when enigne is cold.

So between 5000-6000 is worst than original ECU right? Before and after that is better?

In DC2 is better in al the range, is really good

no disrespect but thats a sure fire way to wreck your engine!!

if you wanted to do this the best way woudl be to put in a fixed resistor instead of teh temp sender for tesiting purpouses then you coudl try it when teh engine was nice and warm,,

I agree.
