Well there haven't been any events worth going to in a while, so I figured I'd work on my car. I've gotten a lot of stuff done in the last couple months.
I've never seen any good write-ups on Haltech's stuff on here, so I figured I'd do it. Here goes...
As many of you know, I built a Megasquirt modified to control ignition also, and have had it on my car for a few months. It was a great setup, worked very well for what it was. Long story short I talked to haltech and after a lot of thinking, I decided to try it out. I went with an E8, with a flying lead harness, and LS1 (corvette) individual coil ignition.
The build Quality is incredible. One look at the board in the ecu was all it took to convince me. There are easily 10x the number of components in the haltech than the MegaSquirt. That's how many more functions it performs, easily. Dave at Haltech actually installed the harness for me, and let me tell you, it's incredible! He heat shrunk every inch of wire to seal it better than the stock harness, and covered about 90% of it in flame retardant material. It's amazing.
I decided I wanted to run the LS1 coils because they are about the most potent mass produced coils available. They are NUTS. Getting bit by them hurts like hell! They have built in ignitiors too, so no need for another ignition module to control them. Paired with the custom MSD 8.5mm super conductor wires I made, it's pretty much the most bad arse ignition system you can get. And the haltech runs all of it. The wires only have about 40 ohms per foot of resistance, so it's performs just about identical to a coil over plug setup. You don't need to make any kind of custom trigger wheel for the ignition either like I did for my MegaSquirt. It just takes the signal from the stock distirbutor, easy as pie.
My megasquirt had an internal map sensor (on the ecu itself) which is an ok design, but requires you to run a vacuum line into the cabin to the ecu. It's just a design prone to failure. The E8 uses an external sensor which is much better than the internal design, and response is better because the vacuum signal doesn't have to travel to the ecu. My map sensor line is no more than a foot long, really cool.
Alright, enough talking, pics now!
the haltech installed. where is it? haha hid all the wires!

ran the harness under the manifold. You can see the wires all heat shrunk.

The LS1 coils and wires and whatnot. Made a cool aluminum bracket for them too.

while Dave did the engine harness, I relocated my battery, slimmed down the chassis harness, and fuse block

Where else would you put the ECU? hahaha I love it!

Impressions: We got it running about a week ago and I've been tuning it since. It literally fired up the first try, and held a rock solid idle with the base map! I was amazed. It is technologically light years ahead of the MegaSquirt. I'm really glad I decided to try the Haltech out. Even with it fully tuned, the MegaSquirt couldn't hold the idle under 1krpms or it would fluctuate really bad and act up. The Haltech will hold it at 500 rpms if I want it to, and purr like a kitten. And this is with no idle control valves or anything! The tuning software is very straight forward, and easy to learn. The E8 tunes by every 250 rpms, versus the 500 with MegaSquirt. This allows much finer tuning, and extraction of extra hp.
And the best thing about the E8 on a four cylinder engine is that it has enough drivers to run the fuel injection fully sequentially and the ignition direct fire. This means each injector fires by itslef, not in pairs like the MegaSquirt, and each spark plug fires seperately, not batched like the MegaSqurit. And with the right tuning, you can get each injector to fire when the intake valve is closed, so when the fuel reaches the valve it is open. This is obviously far superior to two injectors firing at tdc. More hp and tq to be had with this setup. And having each plug fire independently is much better than firing in pairs, because one doesn't need to fire when the other does, which can create problems if you have any extra fuel in the cylinder that is not supposed to be firing.
The E8 does all kinds of other stuff too. boost control, fan control (which I'm running), tach output, wideband control, and about 10 other things I can't think of, it's crazy. You can also select the type of rev limiter you want. I did spark cut on all 4 cylinders at the same time, so it's gonna sound like all hell has broken loose, with complementary fireballs! rock on!
Cliffsnotes: the E8 ROCKS! I'm REALLY stoked I got one! If you want the most from your engine, there's nothing better. Period.
I also got some JWT cam! I can tell once I get it all tuned, they are gonna make it a whole new engine. Thanks to them. I'd suggest anyone who wants cams for their ka, get JWT. I should be getting on the dyno by the end of this week, so we'll see what the new setup makes. I'll be sure to post up the dyno!
Anyone who has any questions about their ecu's or capabilities, contact Dave at Haltech USA.
