i fried my chip a couple weeks ago and got a temporary one from a friend. since then my car has been falling on its *** at a around 5500-6000 rpm. i ordered a new chip from kenji specifically for my swap and mods. got it in today and now my car is running lean as *** even with my 350 injectors and the fuel bumped up +32 all the way across. it gets a little better at around 3000 rpm but it still falls on its face at about 6000rpm. any suggestions?
Car- 96 civic coupe
Engine- b16a2/gsr tranny
mods- 350cc RC injectors, aem fuel rail, skunk2 pro intake manifold, aem cai, lightened fly, chipped p28 ecu, hondata s200, 2.25 full exhaust.

IMO, it can be one of 2 things. either you need to get it re-tuned or when you chipped fried, it did more damage that you are not aware of (electriacally).

 

well i fried the chip out of the car, i hooked it up to an eprom programmer to try to remove the launch limit(cause im a dumbass). when it put it back in the car it had been erased.

 

for your mods u dont need bigger injectors.

Theres your problem.

And why do u have a chipped ECU and Hondata? Why not just use Hondata?

also, is vtec engaging? damn i've asked that about 7 times in the past hour lol.

 

why larger injectors? I see no boost mentioned. honda uses 240s to run that engine all day long.

but honestly.. why the kenji chip and s200? get it tuned right and you're done.

 

kenji burnt the program to use the 350 injectors. have it chipped with hondata cause the obd1 ecu came chipped, then i later got the hondata. if i take the chip out then it shuts off at 4000rpm. and im about to boost it then get it tuned. and i tried it with the stock injectors too and i was barely able to get around the block. had to stop in the street and put my old chip back in.

im really more worried about it losing power so early(6000rpm), than to why it is running lean. its been like that for 2 different chips now.(losing power that is) someone said something about it could be my tps sensor, any suggestions about that, could it be my fuel pump? still have the stock one in

 

Look for a stock ECU and just use the Hondata...forget about the chips and whatnot.

Are all of the injectors working? Do you have your stock ones you can use for the time being to see if it changes/helps anything?

Good luck man! I hate problems like these.

Take the injectors out, put stock ones in, and run a stock ecu. There is absolutely no need to run a chipped ecu on that type of setup unless you go and have it tuned.

 

If you gave "Kenji" your mod list and he burnt the chip to hold those injectors then he needs to question his ability on tuning and common sense.

Like the others are saying...I would put the stock ECU and injectors back in and diagnose the problem from there.

All in all...are you throwing any CELS? They would be very helpful right now

 

I'm not helping you. I want to see you catch your car on fire.
Anybody else in for the video?

haha i'd like to see a car getting "set" on fire any day of the week.

and those quotes you have in your sig are ufckin hilarious! I've never seen either of those in other peoples sigs. There's like 5 people on this board that post all the time that seem to have the SAME few quotes in all thier sigs. Its good to see something different every once in a while.

i dont have a stock ecu anymore, i converted it to obd1 and sold my old p2p. i put the stock injectors in and it would hardly run at all. anyways, i am not throwing any cels. if so it would be great cause at least id know what the problem could be. I was told to check the tps sensor, distributor cap/ rotars, and the engine grounds. i was told the tps sensor could be checked with an amp meter and that it should be around 5amps. True?

yes, vtec is engaging.

 

put the stock injectors back on. Very VEry SIMPLE!!!!!! OR take the car to an expierienced tuner and have him tune it for you.

you have two choices.

Noooooo, you forgot about #3, which includes some lighter fluid and a match.

 

quit dicking around with these chips, get a stock ecu and tune the hondata for when u run boost. Solve your problems quicker this way.

 

ok, first off the larger injectors are there due to boost plans in the future. That makes perfect sense. No reason why you can't do that. And honestly if Kenji setup the chip to run them it should run fine. He's far from a noob.

as long as you're talking low boost the 350s should be enough.

The only thing I can think of is maybe your fuel filter or fuel pump. (you did upgrade your fuel pump right?)

Tuning should show the problem but it may not solve the problem.

Personally I'd find someone local with a burner to mess with the chip to make sure it's not that.

OMFG!!! I already said several times that i tried using the stock injectors and it barely ran. I HAD TO STOP IN THE MIDDLE OF THE ROAD AND CHANGE CHIPS JUST SO I COULD MAKE IT AROUND THE BLOCK!!!! stock injectors are not an option. AT ALL PERIOD&gt;

anyways, if i use a different chip with my stock injectors i still lost power at 5500 and could see the fuel cutting out on my gauge. so it isnt a problem linked directly with the injectors or the new chip. what do you guys think about the tps sensor being bad?

im getting a bigger fuel pump for christmas from my girl. i could change the fuel filter, its been a couple months, probably time for it.... ill do that and see if it works and then ill get back to you guys. thanks for a real answer that DIDNT involve putting the stock injectors back in which i had already explained why i couldnt several times.

 

a couple of months is far from in need of a new fuel filter. A couple of years maybe.

I'd suggest keeping your foot out of it till you get your new pump. Install it and go from there.

 

stock injectors and stock ecu!!! at the same time!
