Just put CTR cams in my 00 si need advise

[ThrottlebotEM1]

SO Finally got something to brag about! i just put ctr cams and springs in along with my timing belt and water pump (almost 100k yeah your jelous! jk)

well anyways car runs like crap at idle so just for the f**k of it i pull off the fpr vac line, car runs better... SO you'd think id need more fuel well NO not at all.

Put a scan tool to it (with the fpr vac line ON) So found out my fuel trim is at -26% can you say WAY to rich basically what im getting at asking is has anyone had this happen? i would have thought it would have been lean! not rich!

WHat im looking for is feedback and advise in which tuning option i should go with, chip (i have a chipped p28 somewhere), Piggy Bank, or both? i would like to get this thing to pass emissions if at all possible so maybe piggy bank is the way to go?

thanks

Chipped P28 which you have and take it to your nearest tuner. That is the best option.

Also did you set your ignition timing and set your valve lash with the new cams?

 

[ThrottlebotEM1]

Yes i did valve lash is the same for type r as for an si b16, so thats squared away, timing is right now i did a compression leak down test and theres no leakage at all. I put the psi full out and there isnt a cunt hair of leakage!!! ive tried to ask honda for some advise, (before you jump at me) i work at a well known dealership that has three branches so i asked them if you can reprogram the stock computer to like a type r integra maps that is. Gm vehicles are capiable of doing it for example cobalt ss stage two kit can be reprogramed and still pass emissions. THey said they dont have acura details they only deal with honda stuff so ill call my acura dealer and see what they say.


THe car runs chugish at idel and dies if you rev her up. but runs normal with a little held throttle, at 5,5k vtec kicks in and bogs a little and by 6,5k the car starts to pull again. Im pretty sure it needs a tune but honda even said with the cams i have the computer has leeway for compensating for the bigger lift and less overlap. EVERYONE HAS SAID THIS!!! i dont get it!!!!!

you need to get it tuned and it will run fine. im sure you can get a chip that is tuned for itr cams.

 

[ThrottlebotEM1]

yeah i figured it had to be that mainly what im worried about is emissions, our state (Wisconsin) is changing the law on emissions, anything 95 and older wont have to go through emissions anylonger. But what does that have to do with me well anything older needs to go through emissions and there getting rid of most up north non emission areas so more emissions in more counties for newer than 95 so im f**ked if i get it tuned! thats why im asking about piggy banks and double checking my timing and s**t

just plug in a ctr ecu and be on your way

honestly i'd just do that. its pretty much a b16b now so it should run like a normal one. plus then its a stock ecu, so you will pass emissions.

PCT is the code for the ecu you need.

post up some videos too.

You can't pass emissions with a ctr computer. U.S. scan tools cant read a jdm ecu. And you can't use the p28 and pass emissions because it's obd1. Your best bet is probably a vtec controller. I live in NY and i'm going through the same s**t. I'm buying an eg so I can build it up, turbo it, and tune with hondata. My 98 won't pass emissions if I do that.

yeah i dont know if piggybanks are good tho... ive heard bad and good.

for a mostly stock setup it should work OK, at least to get him through emissions

 

[lsvtecEK4]

honestly i'd just do that. its pretty much a b16b now so it should run like a normal one

explain this please

 

[Coutts]

explain this please

they're essentially the same motor. go do some research

 

[lsvtecEK4]

lol alright. ill go do my "research"

as far as "bore/stroke" they are the same. but thats about the extent of the similarity. pistons, rods, even the bearings are different. heads are different as well. you are right tho, they are essentially the same motor, lol

 

[Coutts]

that ecu doesnt care what rods or bearings or head is on there, the only difference in the head is a mild p&p and the pistons raise the compression from 10.4:1 to 10.8:1. really no biggie there.

 

[lsvtecEK4]

yep, and i think we concluded to pass emmisions he wont be using that ECU huh. lol.

 

[Coutts]

honestly, you could probably get 2 tunes. get one on a stock b16 ecu and use a vtec controller to get it to pass an emissions test, then when its not emissions testing time just rockout on a chipped p28 without the vafc

I honestly was thinking this. i actually wont need the vafc if i want to go through emissions as long as the lean rich code doesnt go on. It has only come on once and a while then i delete it and it doesnt come on for like a couple weeks or so.

I really dont get why i need to tune it tho. everyone has said that the stock computer will compensate but its not doing it for me! and im pissed that i took someones word for it.


oh yeah a b16b isnt the same to a b16a engine espessially the b16a2 or (a3) thats in my AMERICAN HONDA lol!

 

[Coutts]

i meant as far as running, with the same cams it should be able to run fine. my friends old stock si (just had your standard boltons) had a b16b ecu and a vafc in the car. we didnt know much at the time but now that i look back we think the car was tuned with the vafc, because we plugged in a stock b16 ecu and it ran like dump and threw a code for running rich on the stock ecu.

wait so you personally witnessed a 99-00 si with type r cams? if so did it chug really lightly at idle and die if you reved it up and let it drop back down to idle cuz thats whats happening. the only way it runs is if i have a vac line unplugged. i tried cleaning my throttlebody that didnt work. tried turning the idle screw on the throttlebody that didnt do anything so i put it back to where it was.

Im not an idiot about cars i mean i just dont understand why it would run like this if everyone says putting ctr cams in a b16 wont effect the way it runs at idle.

 

[Coutts]

he didnt have the ctr cams, i dont think. i only rode in the car and heard vtec once and it was back before i knew a thing about hondas (learned alot in the past year, long store short). i dont think it had ctr cams though, sounded like a weaker crossover compared to what my itr cams sounded like in my old ls/vtec swap (and i know ctr cams are similar to itr cams). sounded more like a pop then a boom like my itr cams (i guess lol) when it crossed over.
