3t Gte Running Of ????

[ke20rollin]

ok ive had the ke20 for nearly 2months. yesterday i found out that this car is running a 3tgte toyota engine, with a HOLDEN camira computer.

has anyone done this? has it been heard of? and what problems can it face?

at the moment its running wayyyyyyyyyy too rich, $30 petty gets only 100k's thats with driving it like a baby

 

also another thing i noticed, the 8 spark plugs are running off one ignition coil. can it keep up? and in the middle of the dizzy cap theres a spark plug cable instead of a coil one ??? am i only running 7 sparks? it does have a large cut out. some1 give me a few pointers.

that computer is the generic holden computer. You can chip/program it to do any thing. It's was the standard efi conversion of the 90's.

 

don't really have much of an answer to the rest.

 

Sorry Trev. seems we studied at the same time!!!

Believe it or not the camira ecu was quite adaptable because of how basic it was, The coil would be like that due to the computer system, What do you mean a spark plug cable instead of a coil one?

 

I would be taking the plugs out and giving them a clean or replacing them, Put some pics up aswell.

 

EDIT: Bamboo beat me.

 

Just looked at your sale thread, The coil lead is fine.

a reply to both trev and bamboo

 

appreciate the info. what i mean is, on the cap, it has two centre plugs and 8 around it. only one of the centre ones is connected, hence the single coil, and the 8 around, one is connected to the centre, ive been to a few mechanics and they got no idea. ill get some pics by tomorrow night or sunday morning

hi ke20rollin you are in luck i know a engine tuner who specialises in this area he has a fj20 808 mazda with the same computer and he has another engine tuner who has a 3tgte running the delco system. i spoke to him this morning he asked if you have a DLSL plug in the harness if so he is quiet happy to do a full datalog scan and tell you exactly what is wrong and if you want him to fix. he located in south sydney if that helps. hear is his web site it is mostly gen 3 stuff on the web site but his number is on there and he is quiet happy to talk to anyone who needs help. http://www.vtatune.com/ and as for the coil thing one coil will only run 4 plugs 2 coils will run 8 plugs it is better to run a single coil as it is so easy to blow up the motor with the second trailing plug firing at the wrong time from what i was told this is the main reason these motors blow up. do you know if the computer is a kalmaker system or a chiped standard computer he has software to do both anyway thanks... PS if you don't have a DLSL plug in the harness it is easy to wire one you can use one from a v6 commy should be able to pick one up for $5 -$10.....

As long as the igniter is external you could quite easily run another coil in parallel with another igniter to double the spark. I doubt this will help your fuel economy, but will give you an even burn. As old mate said, its a rechippable ecu, but not real time programmable. I remember when my mate was into geminis this was a common swap to get efi going, but the silly part is it costs nearly as much as a decent after market ECU to get done. To replicate the trailing spark that RB20 Rolla talks of you'd have to run a proper after market ECU and tweak a rotary trailing spark set-up.

 

Call around a few workshops till you find one with a scan tool that works with DELCO ecu's. If your looking for a stab in the dark I'd try and work out what coolant sensor its running and make sure its within range resistance wise compared to a new one. If unplugging the sensor, making the ecu think its 20 deg C all the time saves fuel, you may be onto a winner. These will almost double your fuel use if the temperature is reading -24 degrees when its 30deg C.

ok I'm only getting more confused, mechanical i can handle, electrical makes me dizzy.

is it possible to run the car with no dizzy, coils only? or something like that.

I'm gonna ask about the info you mentioned, see what i can do.

btw appreciate the help.

Haha sorry mate :bash:

 

Get an aftermarket ecu if you want to run coils, there's no simple way to do it with a an ecu that's designed around a distributor, you'll also get the bonus of proper real time dyno tuning which will get the most power and economy from your motor. As I said, the drama with the camira delco ecu's is that you can't change ecu options on the fly. That said, there are some people around with eprom emulators that they plug into the ecu and allow real time tuning... I remember reading about it on a gemini forum years ago, which was hacked and all the old content is gone!

 

In the EFI department -

 

The coolant temp senor should be a 2 wire sensor that plugs into a water housing somewhere on the motor, normally a green plug. The temp gauge will be 1 wire, and could be near by, but I honestly have never worked on a 3TGTE...

 

The problem with faulty senors is that they often don't trigger limp mode. They can put the ecu in a range of the tune that isn't relevant to the running parameters of the engine due to an internal short. By unplugging the sensor completely you should trigger a temperature limp mode, which will make the ecu's map pick a default temperature value, normally 20-30 deg. If a motor runs better inducing limp mode by unplugging a faulty sensor, you can normally be assured you've got a problem with it. This theory works on most sensors.

beerhead is right you need an afthermarket computer to run a multi coil setup and you will need a custom crank angle sensor this can cost up to $3000 plus just to buy and fit it then tune it and more. that delco computer when setup right is better then any aftermarket ecu around like i said just give john a call at V.T.A tune a call just talk to him he is one of the best around he has being tuning these computers from the mid to late 90s.... i think the kalmaker system can be tuned in real time then the program from it is burnt to a new chip then just put the new chip in your computer and off you go..

gave him a call, he knew his stuff and was a great help. turns out i got two plugs coming from the computer. i got the long one that is for the gm- and a different one connected to the same wiring but with smaller pins. ill put pics up a lil later.

regarding the tuning and such. gonna see what i can come up with, with jhon. hopefully we can get things kicking right.

 

worst comes to worst itll be aftermarket. according to an engine tuner i saw he said a haltech will plug str8 in. leaving it as a last resort.

 

pics will be up shortly guys, again thanks for all the help
