worth it isnt it bro

just a question tho Angel, did u use a restrictor on ur turbo oil inlet? and does the HEC715 coil hookup any different?

No
Use 3.5 Ms dwell time, even if ur using a 008 (BIM137) trigger.

ok so its straight forward then, thanks

yer M8, strap it on, grab the HT wire and hit the key!
Knock urself out! (which you will!) Bwaaahahahahah!

MEC series are the "correct" coil series to use but HEC seem to work just fine. I use both.

ok so whats the diff between mec and hec? the mehcanicn broke my coil so i needed a new one dammit

I cant get a definitive answer on this on Matt, Ive heard various stories depending on who you speak to. To be honest, Im not that interested as I like to use what the ECU makers reccommend.

Some say the HEC are "High output" and the MEC "Medium output" Altho I dont go along with this.

Another one is that the HEC series coils are specifically for Ford CDI ignitions.
This might fly as the V8 Fairlanes that have a CDI have the HEC coils specified.

However, all the various ECU makers and tuners quote an MEC series coil.
Specifically the MEC717.

I tend the think that the different numbers are prolly different packaging and mounting choices. Again, I cant say definitely as ive not bothered to research it thoroughly.....perhaps I should?

Anyway, If you have an HEC coil, use it but if you have a choice, Id go with an MEC series coil.

Happy sparking

lol i only went the hec cos angel was running it and he runs a LT8 as well and i would have to wait for a jacobs coil, and bursons were extremely unhelpful as the E15et is listed but no coil is listed for it in the bosch catalogue

I had the same trouble when I went to ShitObarn, the guy asked me if i was sure that it had a coil...

bahahahaha yeh if it aint in the catalogue it doesnt exist in real life obviously we must just be stupid eh lol

Yer Ive discovered that in the past where they have listings for the ET but no actual parts listed agains them??????? Go fucking figger this?
Even the Bosch coil catalogue lists the ET but not a coil for it.
Bah!
What trigger are you using?

um ignition is not my strong point hahaha its a lt8 ecu using stock ignition so i woul day stock trigger? maybe ? lol

That little round transistor shaped thingy attached to the coil?

yeh thats the one lol got on of them its s stocker

should i get a better one cos like i mean iver wasted enough money might as well keep going

Ahh K, yup. Thats termed a "dumb" style trigger. Ie: it will trigger the charge the coil at whatever time it is set to in the ECU.
You just set your dwell time in your ECI (either S1 or S3, can never remember) to 3.5 Ms.
If you find you are getting some missfires at extreme boost, you could add say .5 of a milisecond and not get the coil too hot.

A "smart" trigger, like a Bosch 008 (now a BIM137), has a think about things and sets the dwell time at what it "thinks" is best.
They are going out of favour lately as sometimes they are stupider than what they think they are and tend to supply too long a dwell time to very "fast" (low impedance) coil and the result is a whopping fucker of a spark but overheated coils that can fail.

I discovered this by accident with my Hyundai coils which are very "fast" coils which gave out a spark that would easily start a bushfire but the coils and triggers ran very hot, like seriously hot.
I experimented with dwell times and settled on 3.75Ms which still gives a whopping crack of a spark but keeps the coils and triggers cool.
Not very scientific approach but it seems to work to date.

ok kewl yeh from memory dwell time is 3.5ms i didnt change that stuff the microtech map is a copy of the original map with some timing taken out. thanks for the help
