haltech e6k: base maps for 1ggte?

[ekoston69]

has anyone got a base program for the haltch e6k to run a 1ggte? Just need to get my car going so i can get it down to be properly tuned..

cheers

I hvae only an ignition map, and even that would probably be useless, but Haltech are normally good at providing base maps.

[ekoston69]

yeh haltech doesnt have one unfortunately.. Im gonna try and use an rb20 map and edit the ignition setup. Does anyone have a screen shot of their ignition setup screen for the 1ggte? Most importantly the trigger settings.. Will be using the standard dissy as a cas and an rb20 ignition module to power 7m coipacks. Need things like trigger input (int. reluctor?), trigger gain, trigger mode, trigger angle btdc, trigger type (multitooth?), home input, home gain, number of teeth(24?),tooth offset, spark mode (direct fire im assuming) and output edge..

obviously output type and coil charge time would be the same as im using an rb20 module..

any help would be much appreciated

ok got it mostly sussed, im just not too sure about the trigger angle btdc setting.. could someone let me know what this angle would be? Haltch manual says its the angle btdc that the ecu will be triggered, and that it determines the base timing? Perhaps its the point on the 24 tooth wheel that is triggered 1st? Anyone help me out?

there's 3 sensors in the 1G dizzi - 24 tooth & 2 x 1 tooth i think.

All those sensors are VR (reluctor) types.

Does the haltech ask you how many teeth on the 'multitooth' wheel?

Are you using the dizzi and stock coil pack?

If you are direct fire of 3 waste-spark coil packs - then you need a home signal that's either provided by removing two opposing teeth off the 24 tooth wheel or using both sensors on the single tooth wheel and the 24 tooth wheel for rpm sense only. You need a home signal every 360 crankshaft degrees not 720 (which is what one rotation of the dizzi gives you).

If you are direct fire 6 x ind coil packs - then you need a single home signal every 720 crankshaft degrees - so only one of the single-tooth sensors is used along with the 24 tooth sensor

The home signal is the offset between the single-tooth sensor triggering location and TDC (at cyl #1) on the crank. Not sure what the Haltech prefers but my ECU has a ~60 degree trigger angle to allow reasonable processing time before triggering the coil and firing hte injectors.

hope is of some help, cheers,

thanks heaps, thats some helpful info. The haltech does ask how many teeth on the wheel which i have set as 24, and a tooth offset which i set as 5. I will be using 7mgte waste spark coilpacks and an rb20 ignitor to fire them. From what ive seen people use an angle of around 65ish degrees btdc, which is probably what ill try, and then adjust the dissy itself to match it up properly with the ecu, after locking the timing. Fingers crossed i guess

cheers

what's providing the home signal?

[ekoston69]

i guess just the standard reluctor references?

[thechuckster]

so all the sensors from the dizzi are wired up to the ECU?

fwiw: more info about the trigger pattern on toyota (denso) dizzi can be found here:
http://www.autoshop101.com/forms/h24.pdf (793Kb PDF)

see pg 13-14 for various trigger wheel combos (and expected output).

You'll be looking for the G-signal from the single/double tooth wheel - the timing for it will depend on how you setup the dizzi. If you (after removing the dizzi cap/rotor) rotate the dizzi around and see when one of the the single/double-tooth-wheel teeth points at the sensor - you can then look at how for you are from TDC on the crank - this will the offset angle.


edit: almost forgot - the 1G tech info thread is also well worth a read

thanks mate, that cleared up alot! pretty sure ive got it all sussed now. havent actually wired it up yet was just wondering how to go about it and setup the software etc. Fingers crossed!

cheers
