Right peeps im new to this...

I have a b16a 1992 civic hatch (Eg6 sir)....

Ive had a look through the forums for an answer to many of my questions and as Honda-tech are asking me to get involved i thought i would ask for my self


Ok i have slight hesitation when accelerating from around 2-3k upto Vtec and just smoke when accelerating throughout the rev range? Not massive amounts just a smog really.. ive looked at the forum for answers but there are so many suggestions people are saying it could be, and i wondered if over time someone has narrowed it down to just a thing or two?

Ive checked s plugs and ht leads but not checked ignition timing yet as i have no clue how, timing belt seems right as she starts up and drives fine, its when she's warm when its the problem.. And ive only noticed the smoke over the last few days to be honest.

Ive changed spark plugs, oil and gear oil, shes got a 421 mani and decat and a jracing induction.. Can any of these be the problem?

Shes running a spoon sports ECU as well (limiter at 9.2k) can this cause the problems? Is she just running rich? Im not even sure if this was a plug and play ecu or if the previous owner had to tune it ?.. I live in england and havnt a clue where would be the best place to take her for a tune up?

Ok so lets get to the point, shes seems like shes lagging when i really put my foot down but it only lasts for a second, after that she will go all the way no problem. I only notice it in 2nd and 3rd gear.. What is causing this? because it can be quite annoying when pulling away, having to slow down just abit to let the lag go, and then accelerate with no problem.. Also as mentioned above ive noticed abit of smoke in my mirror when driving down the motor way, what could be going on here? Its just a smog of smoke no particular colour i dont think, should i use a fuel treatment to clean some bits or is this more serious?? Can someone advise me what would be the first steps to take ??

Im new to this, an really keen to get stuck in, were all here for the love for cars and was hoping someone can help me... Can anyone suggest anything or shed some light in this area?? Much appreciated if you can

So you have a cheap chip off eBay and they labeled it as a spoon ecu. I would def junk that but it sounds like you have other problems and your motor needs a rebuild. The spoon chip is a possibility why your experiencing hesitation.

Eg6SIR-Phil

Haha oh nooo... Its a genuine spoon one im sure, Blue spoon seal sticker on the side and imprinted on the front.. Be gutted if it is a fake, ive got a recipt for fittting but cant bearly see the address its so old.. Dated 2010 tho .. also in my investigation i found a wire coming off the gear box which looks to me like the previous owner forgot to unplug when changing it and he's bodged it back together, literally 2 small wires of the hole wire still attached!! Could that cause poor connection or bad earth?? Had her running and she happy revin at 800 ish with no idle up and down problems .. And my mate said when he was behind me that theres not much smoke like i first thought, its just a puff at high range and thats it, like just as i change gear :/ .. Is that something to worry about? Ive herd some vtec's smoke a little but not all, it depends how its been treated and maintained..

did you check the TPS ? can you try a different ECU ? . interesting as spoon has never made a whole ECU/EMS like you are suggesting.

Eg6SIR-Phil

I havent opened the ecu to see what ems is in there? .. Is the ems located in the ecu? or some where else near by? All i have is a casing i presume where the previous ecu was located, and its a spoon one .. All wired in correctly no loose wires missing or disconnected, its in there snug as well not like a passenger could kick it or anything.. :/

Eg6SIR-Phil

And no havnt checked the throttle position sensor yet

B_Swapped93

EMS: engine management system like a AEM EMS or Hondata s300 or Neptune RTP it's not a "thing you look at/find". either way I would seriously try a different ECU and check that the TPS is to spec. btw how much was this "spoon ECU" again spoon never made an EMS like you're suggesting.

Eg6SIR-Phil

Im gonna have to take a pic of this and up load it..

Cause i understand what your saying but i dont understand whats going on with my car!! I mean it must be running somthing if it starts and all the lights come on and turn off and i can drive and that..?? I dont understand whats going on till i look again.. Il take a pic and upload and maybe you can see whats happening..

HondaPartsHero

You need a tune. Your running a "Spoom" ECU (made for non boost engines)
on a super charged car and expect it to run fine? Get a tuneable ECU and get it tuned by a professional before something worse happens.

Eg6SIR-Phil

Yikes!! Best do somthing quick.. And i found a place not too far from me called performance auto works.. Get them to check every thing over.. I was hoping it was somthing i could maybe do myself but obviously not, thanks for the info

Eg6SIR-Phil

Ok I've uploaded a pic of my ecu to my album
not sure how you put it in a thread :/ .. Took it for a drive since investigating and nothing seems wrong now after sorting that wire out.. Seems like shes running alright.. And didn't hesitate at all! but it was only a 30 min blip .. Gonna take tps out tomorrow and maybe give it a clean, also i might buy new ht leads and check ignition timing also ..

B_Swapped93

ummm hate to break it to you but that IS NOT a "spoon ECU" lol looks like someone slapped non matching spoon stickers on it and sold it. again Spoon did not make a EMS like you're claiming . it probably has some pos chip in it that is making your car run funny, as speedjunkie said.

B18C5-EH2

1. Spoon did make ECUs back in the day, but honestly with today's technology in programmable chips and custom tunes Spoon ECUs are a total waste of money.

2. Maybe I missed this somewhere, but can you list the total setup for the vehicle? Engine, trans, mods, etc.

3. The two wires on a manual transmission are likely for reverse lights - no big deal, and should not affect engine running.

4. Regardless of the setup - GET THAT THING TUNED. If it is a Spoon ECU you can sell it off for some decent loot to a Spoon *****. Either way I'd either get your Spoon ECU rechipped/programmed, or buy a stock cheapo P28 ECU and have it socketed/chipped/tuned on a dyno.

Spoon ECUs - authentic or knock-off Ebay stuff - are generic tune that is not ideal for any ONE setup. They are general specs that would have likely been ideal for a mildly modded 1.8L engine, not a B16A.

Help us help you - list the detailed set-up please.

HUmmmm smoking and running like crap after it warms up. Sounds like the head gasket could be going and yes junk that ECU and get a real tune done.

Eg6SIR-Phil

Ok sounds like i have some work to do then, p28 ecu is next purchase.

Cant be the reverse lights as they still worked when i disconnected and re- soldered the wire together :/ i unpluged it from both ends and rewired both sockets, but since then last night i took it for a spin around the estate and all seemed fine, it was only a 30min drive. But ecu still going ahead.

I just cant understand why after owning her for 3+months now shes started to play up.. Everything has seemed fine up an till this weekend just gone.. Just hesitated and choked abit and its like she caught an illness!!

Also regarding set up i need to go through my invoice book to find the mods and get the name list on here, i dont want to miss anything or spell anything wrong which might miss lead anyone..

Thanks for the info on this, if anyone else has maybe experienced this or same problems feel free to post! Cheers

Eg6SIR-Phil

Found out its a genuine spoon p30 ecu product code 37820.. Around £250 second hand and near £600 new.. Are these any good? Will i be selling something better then what im gonna buy (P28 and tune it) has anyone had one before an got rid cause it was s***.. But im still gonna go with whats said above unless someone has any more info??

Eg6SIR-Phil

What i know of the Cars spec:
B16a engine
Y21 lsd gear box (from CRX sir)
421 manifold
Decat
Spoon sports full stainless exhaust system
Wale ***** j's racing induction and k&n filter
And this flipping spoon ecu, unsure what ems is plugged..

Thats what i know is on it, but need to go through my invoices to see if the previous owner did bits to her :/

Eg6SIR-Phil

Just to finish this thread off, ive ordered the p28, cheapo £100

Also cleaned the throttle body and all the sensors and thought i would disconnect the battery, sorted that out and went for a drive, she hasn't hesitated yet and i did that at 3pm this afternoon with no change to the ecu.. See what happens over the next week

nealnanoHX

I would be a pretty rare case if that is a real Spoon ECU and even if it is you are still better getting the P28 ECU and having it tuned even if it is on something cheap like Crome. Ok I thought you said you had a Jackson Supercharger on the motor now you are saying it is a J's Racing Whale *****?

Eg6SIR-Phil

Ok thats what im doing.. No i didnt say jackson supercharger "Ive changed spark plugs, oil and gear oil, shes got a 421 mani and decat and a jracing induction.. Can any of these be the problem?" .. I admit i didnt say wale ***** but i didnt say supercharger, anyways thanks for the help on this .. Ive even found a specialist with 25years experience in ecu chipping and he said he would help me out, every things coming together ..

nealnanoHX

Since you said your cars smokes I would do a compression test.

speedjunkie_g35

I highly doubt you have a spoon ecu. I would have saved money and used the ecu you have already. If i remember correctly you have a b16a ecu so you could alway remove the jumper and run of the stock tune or have that ecu tuned for you motor.

Eg6SIR-Phil

To be fair im not 100% if its genuin as people are saying not real, and others disagree and thunks its genuin cause of the serial number etc, im gonna spend few hundred getting the p28 tuned to my setup, and as mentioned above il get a compression test done.. Hesitating has stopped since ive cleaned the throttle body and sensors, im gessing i had a sticky butterfly valve or the sensor couldnt read how much air was going through and maybe not providing enough fuel for the engine? I dont no but its stopped now thankfully, thanks for everyones responces
