Hello to all honda owners all over the world from Hellas!!!
I want to apologize if some words make you a headache and i will try to be detailed so all of you can understant and help me and share if you have the same experience like me...

To the point:
I have a 97 civic coupe since 2006 stock motor non v tec and then i make my first swap a b16a from eg6. There was a complete swap. That car mechanic make a swap also in my harness to add the vtec and some other wires. Everything were good. Since the i have make many swaps b18c4, b18cr,b19 pro2 and in my final set up i return in b16a2 but with a gt3076. The ecu is a p30jdm with no hondata or other upgrade ecu. The now car mechanic decided to put the fuel injector clinic(fic) injectors about 1150cc with stock chip in ecu but the tuner told that i have to put a hondata to work better. He make it work perfect. I damaged the motor from a false shift i put 2nd gear from 3rd and the motor blow. I fix it and with rebuilt he changed the engine harness with a complete harness from a 97 ek sir 1600 vtec or vti called here in hellas because it has no cuting anywhere and put an ecu adaptor from obd2 to my jdm30.

since then until today the car has some problems like:
When the engine starts the gas in wideband is too rich and keeps to 1500rpm.when i push the gas pedal the throtle body stucks and the gas goes to 10.0 and if i put and leave many time the engine go off and smels gas every where.
after one minute i try to put the engine on but it goes on with hard because a lot of rich of gas. I leave the car runs until is getting warm and opens the ventilator and waitin about 40-50minutes. When i want to go with the engine warm the throtle stucks al lot. When i want to push the pedal for full throtle after 5000rpm where the vtec engaged the vtec won't engaged i listen the turbo and the gas goes to 10.0 and in 6500rpm it makes a boost cut.

thats the problem from cold to warm.
the strange is that when i turn off the engine and turn it on again. Everything works like factory no stuck throtle boby v tec engaged in right rpms and no boost cut.
this problem apeared since i change the engine harness all sensors are tha same like before. I change another ecu but the problem exists.
Car mechanic told me that the injectors damaged because i use the ecu with crome chip and with no hondata chip.but the injectors go for inspection.and everything are good.

any help would apreciate. Sorry for the long text and hope the text is understanding...

thanks a lot 😀😀😀

 

Tuning is the key. You have made two fatal errors: 1) An engine with the mods that you have really needs a better engine management system than a chipped ECU. A chipped ECU is better than a stock one, but you need to take advantage of the newer tuning solutions to really make the engine work as it should. 2) Just because you swapped a B16A with another one just like it does NOT mean that the tune will still be perfect... every system is different, so you need to re-tune. There is no good reason for the throttle body from the old engine to now stick on the new engine... so I fear that you have left some information out that could be useful. IF the answer is you have a larger throttle body... this change makes a HUGE difference in the tune and could explain much of what you are experiencing. A wiring change can also alter how the ECU behaves, so again... TUNE.

Good Luck.

 

Thanks for the quick reply!!! ������
Let me tell you my set up to help you better and sorry for miss understanding from me..
this set up has retune it again in case to work well...
so here is:
B16 block
82mm pistons cp
block guard supertech
eagle rods
b16 head without port and polish
b16b cams
0.5mm ferrea valves,valve springs and retainers
skunk 2 intake
b18cr throtle body
1150 injectors fuel injector clinic
b18c fuel rail
aem fuel regulator
motorola 2bar map sensor
aem 320lt/h fuel presure
b18c oil pump
full race ramhorn
tial 44mm waste gate and blow off valve
gt3076 0.82ar turbo housing.
the ecu is a p30 jdm with chip tune it on crome gold.
a plx egt and plx afr and avcr boost controller.
All sensors are the same,same program everything is the same. The only thing changed is the engine harness and the ecu adaptor harness nothing else.

the strange is that when the engine is cold it has a bad cold start and if i push the pedal the gas is too rich and don't hold the engine and turns on and smell gas. I have no leak gas i checked. When after 3 minutes i turn the engine on it turn on hard and if i don't push the gas pedal it works to 1500 until it gets hot and the ventilator turns on. I can take it for ride but i have no vtec in 5100rpm and the turbine is trying to push the afr shows 10.0 and in 6500 almost i have a boost cut and the throtle stucks every time i push it.
if i turn off the key and turn it on again with the engine hot it run perfect and everything work perfect with no issues.
as long as the engine is hot and after a half an hour i have turn it off and turn on it works perfect no issues.
when the engines works from cold i have no check engine light.
tps is calibrated with multimeter and the cold start valve is cleaned. Every sensor is ok have been checked. After engine harnes the problem began.
in about 2 months i buy a hondata s300 to tune it again.

hope i helped with these details..

Thanks for every answer!!!

 

You are helping put your mechanic's children through college.

 

Wish i could do it... the mechanic told me just to change injectors with lower cc's... nothing else. Suddenly the injectors i have this moment died because of the ecu. But the ecu and injectors are fine...
that is the reason i make this post if someone has a a same issue or similar situation...

 

So
But
How is this verified?

 

It was heronic ...
my mechanic told me that the injectors are dead/off/mulfuction sudenly.
but when the engine warms and close/open the ignition switch everything work fine.
I went the injectors inspection to see if they are ok because i do not have money to spent without a reason.
maybe my writting will conflict many people....

 

you didn't answer my question, how did you verify they are ok "question mark"

 

I sent them for check and the guy there told me that are ok and the 4 injectors.
my mechanic told me told me that when he sent the injectors for inspection he told me that they have problem... but the car runs good after the engine warms. When the engine is cold they don't work well and the vtec also. The bad injectors is conclusion of my mechanic not mine. My check shows that are ok...
