92 ls into 89 hf ***NEW PICS***
 

ok so there are a few vacuum peices im not sure if i need or not.

got rid of the charcoal canister so i just let the one tube that comes out of the firewall vent to the atmosphere correct?

also this:

Attachment 30247

i took the map sensor out of there and ran 1 line to the smaller nipple on the throttle body

what is the other sensor in this cluster ---- and do i need it? there is a plug for it.

also what the hell is this:

Attachment 30248

im talking about the thing all the way on the right, next to the valve cover, says japan on the top of it. has the 3 wires coming out. it plugged into my harness and there is a little nipple on the top of it, do i just run a vacuum source to it? hmmm

Re: 92 ls into 89 hf, do i need this? *PICS*
 

thats an EGR valve, see in the first pic that solenoid with the green on it, vacuum from manifold to that, then to the EGR valve. thats it.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

what ecu are you using to run that. i would assume pm6. if so then dont worry about the egr system. just leave the valve on the intake manifold or make a block off plate

Re: 92 ls into 89 hf, do i need this? *PICS*
 

Automatic LS engine, sexy.

If you get CEL 14, idle that fluctuates as you push in/out the clutch, etc, ignore these fools and contact me and only me. I am a master of the 88-89 HF peccadillos.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

how in the ---- could u tell it was automatic? doesnt show the tranny or nothin ???

Re: 92 ls into 89 hf, do i need this? *PICS*
 

i think its a manual. there is no place for a kickdown cable

Re: 92 ls into 89 hf, do i need this? *PICS*
 

Only EGR equipped LS are automatic transmission B18A1's.

Trust me, guys... if it's old, beat down, and has seen better days I know all about it.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

speaks the truth.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

not doubting that you know your ----, i figured there was something else in the pic that said automatic. what did they do for downshifting the autos back then?

Re: 92 ls into 89 hf, do i need this? *PICS*
 

Solenoid controlled via TCU. MAP and RPM feed where shared between ECU and TCU, IIRC. Pretty caveman setup, actually.

I swapped out the clock crystal in a TCU once for a guy with one hand, so he could have higher shift points, since he couldn't do the 5 spd thing.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

oh, i see

Re: 92 ls into 89 hf, do i need this? *PICS*
 

hmmmm... came with a 5spd ecu and tranny from a 92 DA, so it was obd1. not sure if the obd1 B18A1s had an egr or not so yeah... im running an obd0 pr4, soon to be chipped with turboedit. can i delete the egr with turboedit? also what about that evap sensor? it shares a plug with some other faggot sensor im not sure of what it is. the first reply said all i need is the green piece from that cluster vacuum gayness so that would mean just leave the plug for the evap and the other sensor unhooked? hmm doesnt sound right.

as soon as my obd0 ls dizzy arrives in the mail i should be firing this mofo up.

so far all i have hooked up from that mess pictured above is the map sensor, just one vacuum off the little nipple on the throttle body to the map just like ive seen. waiting on my freescale 2.5 bar to come hehe.

anyone have any other info they would like to share?

Re: 92 ls into 89 hf, do i need this? *PICS*
 

You delete EGR by leaving the EGR valve disconnected from vacuum, and don't plug up the lift sensor either. The auto IMs are a little longer in the runner if I remember right, so you get more low end torque, your best bet is to swap for a manual IM off any LS '90-00. Don't pay a dime for one, stock LS ---- should be and often is free.

You can remove all that throttle cable dashpot and vacuum crap on the front of the plenum, while you are at it, it serves no purpose and likely doesn't work correctly anymore with how old it is.

There is no code provision for EGR in any of the softwares, or on any of the ECUs that you would run. Forget it existed, aside from snipping the EGR signal wire at the ECU (part of the CEL 14 clusterfuck). I'll try to look up the exact pinout of what you need to cut to make 88-89 HF be completely OBD0 MPFI/Si plug and play, I have it writen down somewhere.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

holy ----.... damn. well thanks a lot.

now the lift sensor? im assuming that is the green ---- box?

here i numbered the ---- to make this easier.

http://img295.imageshack.us/img295/3883/shitrn3.jpg

1. map sensor - simple vacuum to nipple

2. evap sensor? - i got rid of that fag charcoal ---- so that leaves one nipple open? do i just leave it and plug it into the harness like normal?

3. green ---- - no use since the egr will be unhooked correct? sweet.

the sensor with the ? mark over it im not sure what it is, its getting plugged in since it shares the same plug as the evap sensor so yeah. thats pretty much my last question.

4. no idea why i put a #4 there.

so im just going to leave the egr complete unhooked from both vacuum and the harness and that is over and done with. also going to rip all that dashpot ---- off.

this would be easier if i had it running but im just doing all the little bits i can so i can have this thing running and boosted by the end of the month.

p.s. - got my mani/turbo on, EG rad and intercooler mounted and some other ----... after its running ill be chipping the ecu and throwin in my 450s. sorry had to add that haha.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

Don't forget on older LS's they used a solenoid valve feeding the vacuum line to the fpr...should be one of them in that clusterfuck.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

cant i just run a vac line from anywhere on the intake manifold to the top of the fpr?

Re: 92 ls into 89 hf, do i need this? *PICS*
 

The only plug attached to the engine that needs disconnected is the three wire plug for the EGR. Pretend that ---- doesn't exist until you get around to deleting it so that it doesn't exist.

The only plug not attached to the engine that needs to be hooked up is the MAP sensor.

Plug in the ECU, she'll run.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

u guy are speaking greek, to me :P

i know absolutely nothing about wiring, though it doesn't sound too hard to learn

Re: 92 ls into 89 hf, do i need this? *PICS*
 

alright sounds good i took off all that dashpot stuff and unhooked the egr plug. ill be turning the key once my dizzy arrives, hopefully tomorrow.

now there are about 8 holes on my intake mani i have to plug up hah!

wont i be throwing a code for those 2 sensors i leave unhooked? evap and whatever else it is? (the ones nestled deeply in the pic above.)

Re: 92 ls into 89 hf, do i need this? *PICS*
 

The purge solenoid, the homosexual valve, and the faggot-ass-does-nothing sensor don't throw codes or effect how the engine runs. It's just misc support systems for emissions stuff that you don't really need. Cold hard fact of the matter is most OBD0 and OBD1 Honduhs w/ less than 80K miles can pass 4 gas emissions tests with all that stuff stripped off, and no catalytic converter. Most of it is for the EPA's benefit, much like chrome valvecovers are for car show judges benefit; both do nothing.

;)

Seriously, she should fire right up. Your main hurdle is I'm too lazy to dig up the pin out changes, or email Speedy about them, for 88-89 HF chassis so you don't have the (cosmetic) CEL 14 and minor idle fluctuations when you depress clutch pedal.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

run fpr line
run map


dont connect egr just plug vacuum port keep auto manifold not gonna really make a difference. Egr is only found on auto b18a1 no biggie


dashpot belongs in the trash


make life easy

Re: 92 ls into 89 hf, do i need this? *PICS*
 

update*

it runs! did what you nigs said and presto she started once i popped the dizzy in. getting code 17 which im told is VSS? im guessing its because i didnt loop the lines coming off the vss... ill try that and see whats up. didnt know you could get a code for vss on a car with a mechanical vss. also could i have an auto pr4? is an obd0 pr4-something-A02 thought it ending with A02 would make it 5spd?
v

Re: 92 ls into 89 hf, do i need this? *PICS*
 

A in the last three digit code means America. C for Canada, J for Japan, and if it's a number it is called a "world part."

The VSS on the ED chassis is the backside of the instrument cluster, and is driven by the speedo cable. If you have a working speedo you should get no CEL 17.

PS - congrats. :)

Re: 92 ls into 89 hf, do i need this? *PICS*
 

word code 17 no speedo hooked up


a52 is an auto pr4 ecu. It can be chipped also running 2 guys around my way with mighty all motor zc's with turboedit codeage

Re: 92 ls into 89 hf, do i need this? *PICS*
 

yeah well the speedo worked when i drove the car into the garage so i never unhooked it. could i have possibly put the cable in the vss wrong? so a52 is auto, A02? hoping for 5spd. btw i know its chippable, thats coming next!

Re: 92 ls into 89 hf, do i need this? *PICS*
 

More than likely the cable probably popped out of the vss...they're supposed to have a clip on them to hold the cable in place, but most times they get lost. I just zip tie mine down tight.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

only auto ecu I have seen was the a52 chipped it like any other obdo non vtec ecu

Re: 92 ls into 89 hf, do i need this? *PICS*
 

yeah just dont want a check light for auto tranny, heard that you cant convert obd0 ecus from auto to 5spd

Re: 92 ls into 89 hf, do i need this? *PICS*
 

heard wrong


I was reppin a chipped auto pr4 in my crx for like 3 years back in the day running a techtom all motor proggie done by one of the og ecu dudes

Re: 92 ls into 89 hf, do i need this? *PICS*
 

update

everythings good, no CEL! runs perfect.

here are some pics, im posting the rest of the turbo progress in the thread linked as the new boost in my sig so check there if you are interested... but you probably arent so ---- you.

mexi gold


good man got rid of the the rats nest of black vaccuum tubing

Re: 92 ls into 89 hf ***NEW PICS***
 

Sweet.

HF's are king dick of boosted cars - your power to weight can't be beat, you can slaughter crazy ---- at 225-250 whp, and all the sexy bitches will want to ---- you because you can obviously get the job done.

Re: 92 ls into 89 hf ***NEW PICS***
 

sweet im doing a swap just like this next weekend!, except 01 auto b18b(turbo'd) into 91 crx si, i just need to get a refurbished or good condition cable transmission, those are hard as ---- to find!


quick q.. i just use the wiring harness from my crx and all the plugs from the b18 right? oh yea and i guess i will need obd0 dist too won't i.

Re: 92 ls into 89 hf ***NEW PICS***
 

i used the crx harness, everything worked but i made a jumper for the resistor box, wired on the obd1 plugs and im using an obd0 distributor. i didnt delete the resistor box because i have some dsm 450s ill be throwin in soon when i add the boost.

one plug on the back of the block didnt plug in, i think its the coolant temp sensor.

Re: 92 ls into 89 hf, do i need this? *PICS*
 

Re: 92 ls into 89 hf, do i need this? *PICS*
 

JD, Thats ------- gangsta.

Re: 92 ls into 89 hf ***NEW PICS***
 

oh so you could reuse all the d series sensors except the coolant temp sensor? i was gonna rewire all the bseries sensors.. if not that saves me time

Re: 92 ls into 89 hf ***NEW PICS***
 

yeah dont swap plugs, then what would be point of using the crx harness? you prob gonna need a dizzy conversion harness as well.
