I just did a b16a swap in my 99si. the motor was in a boosted car and i have all his turbo stuff.when i start it idles fine but as soon as i give it gas it just cuts out and won't go past 2500 rpms. all my wires seem to be ran right and my tps and map are all working fine. not really sure whats going on. im prolly forgetting somthing so if i am just ask. any help would be great.

Any CEL codes?

Is the mechanical timing off by a tooth?

civicrunner99

its throwing a cel code not sure which one don't have the toold to check. and timeing is good.

rick_rabies

check it with a paper clip or cut the wires and put a switch there in the glove box
when you need to check the cel you flip the switch wala

If the car is a 99 isn't it obd2? Can you still flash out the codes???

rick_rabies

yes. but i forgot about that. autozone can read the codes for free and tell you what they are. sowy

civicrunner99

idk the paper clip didnt work

Dkober101

just a ponder, but did the boosted motor have cam work done?

civicrunner99

no didn't have cam work. just not really sure what to do

civicrunner99

anyone have an idea

alex22

check your distributer you might think its right but it might be wrong on the wiring trust me............also check your injectors make sure theyre obd2

civicrunner99

im running precision injectors and i have the clips for them and there wired up right.

get the cel codes....your asking people about your car who know NOTHING about your car, try to help us out a little too. stop being lazy and go stick a paper clip in the plug near the ecu so you can read your code(s)

I would guess ckp is not reading right. which is in the dizzy. I had same problem with my ek swap. Although mine was a broken wire somewhere in the loom.

Jus an idea tho

Sounds like the ECU is in limp mode, for whatever reason. What ECU are you running?

TK_209

what does limp mode mean? i have a b16a2 swap in my civic and its doing close to the same things and im running a gsr ecu..{got the car with it}
thanks

B16Drag

TK209, your running a b16a2 with a gsr ecu. You do realize that the gsr ecu was meant for a gsr motor and not a civic 99-00 (b16a2) motor... Get a chipped P28 for a B16 and you should be good. Your car is probably also in limp mode.

JohnnyWash1

A P72 will run a B16--I've done it. The only issue is VTEC crossover, which is at 4500 for the GSR and should be at 5700 for the B16.

As for limp mode, it is the mode the ECU goes into when it reads a catastrophic failure, or when the ECU is bad itself. Basically it reverts to a rich base map and limits revs to around 3000 (depends on what your tach reads).

B16Drag

I'm sure you can run it. But it isn't ideal as the fuel will be off as well as the timing and everything else for it. GSR's also have secondaries. If both cars have CELs and are running like crap and doing the same thing... chances are its in LIMP mode. Bottomline, run the correct ecu for the correct motor and save yourself the headache.

JohnnyWash1

I totally agree. However, I just wanted to clear up the confusion. A P72 ECU running a B16 will not throw any codes or run in limp simply because it was designed for the GSR.

B16Drag

Yup Yup, johnnywash is on top of it.

JUST GET A CHIPPED P28 ECU AND YOUR B16 WILL RUN PERFECT.

The code was intake temp. Im running a chiped p28 on crome. put my buddys p28 tunned on hondata s200 and does same thing. both cars are built almost the same.
