I have bin surging for an ECM for the swap and fond an ECM from a grandprixx 1989 Is this a right ECM for the swap???
It is for my fiero 87 the engine V6 has a manual gearbox The engine I want to put In Is a montecarlo 3.4 V6 with automatic gearbox I want the automatic gearbox to be replaced to a manual gearbox The PCM that came with the montecarlo will not do the job so... I have fond an ECM from a grandprixx 1989 V6 will it do the job
yes thats what i'm using - but it still not tuned properly.. if I'm not able to make that work then i'm going to rewire the engine to run the stock ecm from a 95 grand prix 3.4dohc ..
however I am also running a 2bar MAP sensor for turbo
do you think the ecm wont do the job for my swap. in the future i want to put a charger on the engine but furst tings furst but for now al i want is to get the engine runing
oh it'll do the job - there are a few people using that ECM to run the engine.. turns out my ecm is fried - so i should be able to get back to tuning it as soon as i replace it with a good one.
1997 Chevrolet Monte Carlo V6-204 3.4L DOHC VIN X SFI
Generation: 5th (1995-1999) Country: Canada Producer: General Motors Division: Chevrolet Car Line: Monte Carlo (W-Body) Model Code: Monte Carlo Z34 Body Type: 2 Door Coupe Restraint System: Air Bags for Driver & Passenger Engine Code: 3.4L V6 DOHC 24-valve Model Year: 1997 Plant Location: Oshawa, Canada Production Sequence: 288474
Just want to be certain about the ECM. I have to order it from Canada and the costs are 250 dollar and stil get it here in the Netherlands, and have to bay the harness for the ECM
do you have the harness for the engine? if so you won't need the harness for the ECM - you can repin the connectors to plug into the new ECM (atleast that's how I did it)
price seems hi though - I just had to buy a replacement ECM and it cost 50$

this is the ECM the original that came with the engine
it's connector in tape (do not know how to say it in english)
as jou can see it is difrend than all the others they have four or five connections
and because I live in the netherlands and here almost nothing for this swap I must buy everything in the usa and straighten pay import for it So everything will cost me twice the amount of money than you guys in the usa
I used www.car-part.com for refference.. I'd recommend finding on in there and having it shipped to a friend in the US or canada who can send it to you.
Can you find a ecm#16196401 GTP (3.4 dohc with SFI and MAF) I search on www.car-part.com an the only thing I fond was the ecm but not with the SFI and MAP.
If I know were to order it than i hope someone can ship it to me

I've been talking to the guy who runs www.60degreev6.com about computers for the 3.4dohc.. and there is a possability that you will be able to use the stock computer.. if it turns out you still need one of the other ones i may be able to help you out - i ship things overseas alot for my company ( www.viscoustech.com ) and have never had a package go astray yet

1 Ok sounds good can or is there some info on it that i can work with?????

2 what are the costs for my if you find a ecm and a chip ship it oversea to me ????
I can tell you what I used for mine. It was the earlier (91-93) ODB I ecm part num 16149396. Darth Fiero burned the eprom for me for use with the manual tranny. This ECM is Batch fire so mpg (kpl?) may not be as good as the later SFI setup but it works and I'm not sure you really notice the difference except in the wallet . It is also MAP, not MAF so you'd have to lose the MAF sensor and hook up a MAP sensor in it's place. It does not use the camshaft pos sensor. Also I am not sure if it will work with the EGR solenoid on the later engine, One is digital, on is...........er, not !! You would also need to repin a bunch of stuff on the harness or make your own harness up.
Ps. Mine is a 95 engine so I did not have the egr issue, it worked ok with the one on the engine. I 'think' theogre had a post on here or maybe his web site about how to convert the signal from one to the other (or I've seen such a post somewhere) so you could drive the egr but I'm not sure if it was old ecm to new egr or newer ecm to old egr.
The 91-93 engine came on both manual and auto cars. The only difference in the 16149396 ecm is the programming in the chip so you can use an ecm from an auto car, get the chip reprogrammed and it should be fine. I know others have used other ecms and programs but this is the only one I really know about. Like I say, it worked for me. If you are looking to turbo/supercharge later then you may need to use a different ecm/prom chip program but I don't know anything about that subject or even if you could use this ecm in that setup.
I'm still looking for that ECM/PCM#16196401 3.4 DOHC with SFI and MAF and it can be found I a 94-95 grand prix and the connectors are OBD 1.5
thare is nothing to be found in the netherlands so I need to find a way to order it from the USA. www.autopart.com wont send enything over sea and than i have to find a way to get it to Ryan www.dtcc.cz28.com for the chip
might i suggest that you contact Ryan and see if for a small fee he will purchase the correct ecm with wiring connectors for you, program it and ship it to you?
yes i know but he told me i have to find one and ship it to him .but i cant find one in the netherlands so he cant help me .
he will do the chip for me, fi i got the ECM
The problem I have encountered locally is there are very few of these 94-95 3.4 DOHC-powered cars that still have computers in them; so I haven't had much luck finding these types of computers. I have been in email communication with this gentleman from the netherlands and I will check locally again and see if I can come up with something -- but don't count on it. If I cannot find one locally then he will need to get on www.car-part.com, find one, purchase it, and have it shipped directly to me so I can reprogram the chip and send it off to the netherlands.
Problem is I am so busy lately so I don't have the time to get on www.car-part.com and call junkyards and see if I can locate one. Since I am going junkyard hunting today or tomorrow for other parts, I will see what I can come up with there.

I has took me some time to instal the engine wiring and all and Yes it's starts ,But now I have still some questions about some wiring of the Engine and 'C500 connector of the fiero'
First the C500 connector need to know these wires,
Pos - Wire color - Circuit - Description
H - Brown - VSS high - Feeds buffered VSS signal to ECM when a magnetic VSS is connected to speedometer. note 3 ???? what is note 3 and what do i need to do with it.
And the engine
P - purple-TCC Brake switch - TCC brake.hot in run bolb test, or start only when brake pedal is NOT depressed. dont understand
R - purple - Vss Low - VSS input to speedometer. Connect to magnetic VSS or to ground if using optical VSS and converter. note 3 ???? what is note 3 and what do i need to do with it
Here is a pic of the place where the ignition coil pack is and ecm when all the wiring is competed i will make it look nice

I believe you mean C203 which is the connecter inside of the car located under the console

Note 3 refers to a circuit that you must build in order to interface correctly with the Fiero speedometer. http://dtcc.cz28.com/fiero/fmods.htm That would only be used if you plan on using the ECM to send a signal to the speedo instaed of the original Fiero Vehicle Speed Sensor which has a different Pulse Per Minute rate than the non Fiero trans do. If you are using the stock Fiero manual or auto trans then you wont have to use the special circuit to run your speedo. You WILL want your ECM to know that you are moving though and the wiring to the poper pinout(s) will depend on which ECM you are using
quote
And the engine P - purple-TCC Brake switch - TCC brake.hot in run bolb test, or start only when brake pedal is NOT depressed. dont understand
When you press on the brake, the brake switch circuit opens which cuts off voltage to the TCC solenoid which unlocks the torque convertor. Since you are apparently not using an automatic with lock up torque convertor this will not be used
quote
R - purple - Vss Low - VSS input to speedometer. Connect to magnetic
VSS or to ground if using optical VSS and converter. note 3 ????
what is note 3 and what do i need to do with it
read above about the special circuit that needs to be used if using the ECM signal to run the Fiero Speedo. In a stock Fiero the ECM does not feed a buffered signal to the speedo

Ow and sommeting els On the ECM there is no connection for the MAP sensor, Do i need to install it on the engine and not connect it to the ECM sins there is no connection for it ( will this give the engine trouble)
And when I got the engine there was no MAF sensor on the engine what type of MAF sensor do I need.PS I want to put a turbo on the engine and i do NOT know if this make any difference if i use a wrong sonsor or is this something quite different This is a New for me so I dont know where am talking about
If you look at the diagrams you can see that there is a Serial data jumper C3 C4 what do i need to do with them. and for reading the ECM for trouble code's there is only one wire from the ECM is that corect or do i need more connections and i dont meen the ground and 12 volt to the fuse blok.
Thanks Daniel

On the diagrams i cant find the 4K Pulse per mile wire/conection Daniel
Daniel, That would be pin B 13 on the 94- 95 SFI with MAF Are you using the stock Fiero transmission? IF so then you do not need to use the special circuit because the stock Fiero tranmission VSS puts out the correct PPM to run the speedo correctly. I would connect Pin H on the C 203 to Pin B 20 of the PCM so the PCM knows you are moving.

i'm rewiring to use this computer and will be using an LS1 MAF with it - it will allow more airflow and will allow me to run large rinjectors for the turbo no map sensor is needed if you use the maf between the turbo and the intake

Thanks for the info,
And pin B21 ECM what can I do with that one .Connect it to R of the C203

Okee so i will use that setup,But where can I find the LS1 MAF sensor in what type of car is it found and wat is the price becouse i was looking @ summitracing and the expenses sit between $117.95 and $617.95
