"Parmas" Motor

[Parmas]

Today changed engine oil and coolant and installed the "NEW" Teflon braided pipe for the turbo water line. Also all in cabin wiring is finished and arranged it like it never been there .

During the turbo water line installation I came to notice that the idle control on the throttle body has the coolant pipes missing (In and Out). Then I understood that these were being used to feed coolant to the turbo from the beginning. So I ask are these essentially needed for the idle control to work fine also since I changed the engine management? What are the consequences of these removed?

Also I need to know some information on the Idle control like frequency and normal operating conditions. I attached a screenshot of the page of the ecu software to set this up

I know I'm not using those on my TB

Today I tried to start the engine but it seems there is something blocking the startup since it is stopping cranking after only few seconds.

I tried to increase fuel on the rpm range but still no start. After I came across this describtion of the starter on the manual and it says :

"IN CASE THAT THE STARTER BEGINS TO OPERATE, BUT CANNOT DETECT THE ENGINE SPEED SIGNAL, THE ECM WILL STOP THE STARTER OPERATION IMMEDIATELY"

Then I began to think that since I am operating the starter through the stock toyota ecu and I disconnected the engine speed signal (which is the Crank Trigger Sensor) and connected it to the Haltech Ecu, the stock ecu is surely not detecting the crank trigger and is probably stopping startup. I am not sure about this but it could be plausable.

Now I decided to eliminate the starter by using an external relay and a push button.

Although I am not sure about this so Garm or any other that has changed their ecu should tell if this is true or not.

Here is the current setup

I would like the experts to confirm with me about the Triggering of the engine in relation to Camshaft position.

Main needs are:

1. Trigger Angle

2. Tooth Offset between crank trigger and camshaft trigger

3. Trigger / Home Edge

[Parmas]

All is ready and prepared for the dyno tune. It is scheduled to be within the next week so cross hands all goes well to jump to some nice numbers.

I think I finally earned this after 2 years owning the engine it has not passed 500miles on it!

The only thing remaining is putting on the bumper in place and we are ready to go.

[pimp my yaris]

Looks good. All Business.

[changchewsoon]

time to make some serious power parmas, can't wait to see the numbers on the dyno!

[cali yaris]

CLEAN - you are ready!

Car was brought to the tuning facility for tuning.

For a change we had trouble keeping the engine on idle and was misfiring as hell. The tuner said that probably it is something related to the camshafts \ VVti activation position etc...

We brought another standard engine to compare values of crank triggering versus camshaft positions etc... which are still working on it.

Tomorrow will check the intake manifold and throttle body for leaks just in case. Also need to change the oil turbo feed line since the tuner said it is too wide than normal condtions.

I would like to know what happens to the camshaft position if you disconnect the Cam timing plug (near the alternator) . Would it become fully retarded or fully advanced or a certain degree?

This answer will help the tuner much with his issues!

^ unplugging the VVTi solenoid leaves the cam at 0°. So no advance.

Parmas,

That haltech digital dash is absolutely stunning.

I saw one of these in a rally car the other day and figured I would never be able to have anything nearly as cool as that in my car so seeing it in front of your dash has made me really excited to start working on my engine once the funds become available.

Keep going strong man we're rooting for you.

I agree with you on the digital dash although you missed that was only an opinion of changchewsoon. I don't own it at this time.

[cali yaris]

^ Me neither but I would like to do a digital dash, right in front of me (where it belongs? LOL), someday.

I brought the car to my tuner that specifically recommends Haltech ecus. He worked about 2 days trying to start but the engine persist to misfire and cannot remain idle at all. We checked the triggerring signal and it seems to be inconsistent everytime we try to start the engine. He also tried to vary filtering levels but invain.

My tuner is about sure that the problem might be coming from an issue specifically related to the 36-2 + 3 Sequence Toyota use.

Garm, did you had any issues with your AEM ecu regarding triggering?

[cali yaris]

^ no problems at all, sorry!

[Parmas]

The problem is about sure that is a software issue but we need Haltech support to solve it before we continue.... sooo the car goes back again into my fu..ing garage.

If haltech will not solve it within the next month I have no choice but to make custom triggering wheels for the crank and the cam using Haltech Hall Effect sensors.

I hope this would be the last issue as I am really pissed of about this engine and it is making me sick.

[cali yaris]

oh man that is tough -- so sorry you've gone through so much to get this far, but it's SO close now!
