getting her running

[UZGUNNER]

So I have a 92-93 JDM sc400 motor (no EGR), a harness from a US sc400 and a US ECM that I got from a salvage yard.

My question is what would be the easiest way to get it running. Can I get the EPROM re done in the stock ECM to eliminate the EGR and any other sensors that aren’t mandatory? Or should I go with a megasquirt system and what one?

I feel confident I could handle the megasquirt myself but don’t know if it would be the best route? And can it adapt to the temp changes in New England?

thanks

O ya I also obviously don’t need to pass emissions

just get a stand alone ecu such as a motec or haltech and wire it up

i was looking around and those stand alone ecu's are allot of money. is there any cheeper route?

 

[UZGUNNER]

i don't need anything special.

i would like to add a supercharger in the future soo a ecm that would be capable of doing that would be nice.

 

[UZGUNNER]

can i bypass the egr on the stock ecu?

 

[Cobber]

there is no feedbck to the ecu for egr so no problem in just blanking it off.
Go aftermarket ecu.

Congratulations, your well on the way to having a hand grenade motor...

if you cheap out on engine control and then want to add a blower you need to read up more on other peoples experiences and decide if modifying cars is realistically within your budget, the road your on is just going to cause grief and loss of the money you do have.

ok well i guess for now i can try to just get the stock ecu running.

but then is there a way to i get rid of the cats and 02's?

what would i need to get it going? i know i need to buy a mass air flow meter

 

[Cobber]

Yes you need o2 sensors to run properly.
No you don't need cats if no emissions required
Yes you will need a MAF

The hardest part is finding a flux capacitor but these quite often come up on ebay.

lol well i guess ill just start throwin it together

Go aftermarket ecu.

tis on mine,had to terminate egr plug with resistors (4x22r 2w)..or ecu not happy,fault codes etc..

 

[zen]

just go do it...

nothing like getting hands dirty to learn..(keep eyes open for a spare engine though.lol..)

There is nothing wrong with Megasquirt man. Don't listen to nay-sayers. It is a very competent system and no standalone can compete with its bang-for-buck. After experiencing what happens to these ECUs with age, I would never put a stock 1UZ ECU to use.

 

[UZGUNNER]

Does anyone know what ECU is this and does it have a ECT in it? i cant read the part number

[UZGUNNER]

it has 3 X 4 rows of 10 pins 120 pins in all

 

[gloverman]

Looks like a soarer ECU. Without seeing the complete casing could also be a uzs141 crown ECU. Yes it has an ECT in it. We often refer to it as a 40/40/40. Cheers

so im going to run into a problem because i have a 5spd right? the ecu is going to be looking for shift points i would think.

what the hell do i do now? aftermarket?

 

[gloverman]

It will run fine with the five speed if it is wired correctly. Ive wired about 20 of that ecu with a manual behind them. Cheer

ecu wiring..

Hi gloverman
Sorry to hijack this thread.. Gloverman I have a 92 ecu and a cut loom that I want to run using a manual gearbox.. I have been told that a shielded wire needs replacing.. But the ecu checks out OK
I was wondering if I sent you these parts could you wire up so that I can install onto the motor and run on a test stand..?
Just wondering what it might cost..?
I own a CNC machining centre so if you needed any parts maybe we could come to an arrangement..

Cheers Craig
