Ca18det build

[Ca18det zook]

Hey guys I'm new to ca18s but now I have 2 One is in a Suzuki sierra that is not running has fuel an compression but no spark I've looked on the ecu for codes the red an green stay on this means ecu f**ked right?



Then seconded motor I have was to try make some hp then put it into the Suzuki the hp I was chasing around 300 to 350 ish and wondering what I will have to do to archive that

Thanks

Has the ca18 in the Suzuki ever ran? More info is need on the motors history.

Regarding your 300-350 hp goal, wheel or crank? The link (http://www.nicoclub.com/archives/float- ... guide.html) will give you the run down on what you need to build a CA. As long as you do the preliminary 11 steps then you should be able to hit your goal. People have made alot of power out of a stock block but only with proper management.

Yer it has been running then the alternator s*** it's self replaced it was good for a 2week then it died but a week before it died I put a turbo time on it would that have coursed it to kill the ecu or coincidence
Thank for you help

[chalander]

Have you checked your codes before? U turn the screw fully clockwise while the ecu goes through the flash sequence 1-2-3-4-5, once three flashes occur rotate screw fully counterclockwise and u will then be in mode 3 which will display any fault codes. If this is old news to u then I apologize for being long winded, I've never come across an ecu that wouldn't communicate via flashing its green/red lights.

[Ca18det zook]

This is my first time at reading flash codes I did it one way an the red an green would flash once than did it the other way an both red and green stayed on

You have to keep it clockwise until it flashes 3 times. Please refer to EF&EC 64 and 65 in the FSM.

[Ca18det zook]

I just tried again an the red an green flash once an then nothing els happens

[boost_boy]

You are doing something wrong. It should flash or something. If there is no fault detected, it will flash 5 red and 5 green. If it doesn't, again, you've done something wrong or you have some wiring or ecu issues.

[Ca18det zook]

Hmm what I'm doing is turn the screw fully clockwise turn to start and the red an green LEDs flash once am I doing it right

[float_6969]

Ignition off, should be fully counter-clockwise
turn ignition ON
Turn fully clockwise
Should flash once
WAIT
should flash twice
WAIT
should flash three times
turn back counter clockwise

any codes will start to flash

I would like to point out that the Suzuki Sierra over here was called the Suzuki Samurai.

A 350hp turbo Samurai sounds like the coolest thing ever. Do you have any pictures you could show us?

Oh, also, do what Float6969 says.

[Ca18det zook]

Ok thanks heaps ill give it a go

I do have a couple of pictures but I don't no how to upload them haha

My first bit of coin I have to spend on the motor I'm building is 2000 what would best the best mods to start with .

[Ca18det zook]

I tried what you said float6969 an the red an green LEDs just stayed on no flash

[boost_boy]

Perhaps you've already smoked your ecu or you have it wired wrong.

[float_6969]

Yea, if it's just staying on, you've got some serious issues there. Sounds like a burned up ECU to me.

[Ca18det zook]

Thanks for your help guy I found a mines tuned ecu for $125.00 I played with a test light for a wile had no power at the coils no power at the ingniter dose that also point in direction to the ecu?

[chalander]

Since you have never operated the ecu to display codes before I sugjest trying again with the sequence float explained. Or for a better description refer to the FSM as mentioned earlier

... Please refer to EF&EC 64 and 65 in the FSM.

The ecu may be bad, though, I think you should do you best to ensure your doing it correctly.

[Ca18det zook]

Hey guys I've tryed reading the codes just like it sez to above
Still no luck An I'm running out of ideas to try all heap would be great thanks

[boost_boy]

If you are not familiar with nissan wiring, then you could've very well wired it wrong and/or burned a trace or something. Or you've inherited a bad ecu or your set-up is not wired correctly ro we don't know what we're talking about which pretty much ends the same way for you (a car doesn't run). But seriously, try the ecu in another vehicle to make sure it is functioning properly and this way you'll know for show who or what is the culprit behind your "No-Run" condition.

[float_6969]

Do you mean you're not getting the different flashes when it you turn it back and forth? If not, the ECU is toast. As Dee mentioned, you need to find out WHY it's toast before you put another ECU in there and potentially burn it up too.

[Ca18det zook]

Thanks heaps for every ones help I don't have accsess to another car with a ca18 in it but I do have an ecu coming should be here tomorrow but like yous said it may just burn it to
