Yeah, I keep a close eye on my max airflow.

Without adjustment, I run about 14:1 with the 2.0 ecu at WOT.

I get 80% usually, at the stock redline, but when I was revving to 7800, I could get 90%, lol.

Anyway, those readings are on very cold days, in the summer it is usually at about 70-75%, so no worries on the lean fuel curve.

At 20% addition with the safc, I was at 13:1, so I added a bit more to get into a good torque afr and away from detonation worries.

I cant wait to get this haltech in and running!

 

^^^I can't wait to HELP you get your haltech in and running! smile.gif

 

LOL! You have been doing plenty of helping already, haha!

I shipped it out today, scheduled delivery is the 21st so you should have plenty of time to get it done and shipped back out before christmas right?

Just kidding lmao.gif . Take your time with it, especially around the holidays, however a delivery time somewhere in january would be nice.


In one of the engine tuning books I own, specifically "how to tune and modify engine management systems", it has listings of different standalone ems's and their features. He states the E6X has the ability to utilize the stock ignitors. Is that true? I would assume it is not since you said I will be needing to purchase some, I would assume I need one for each cylinder?

Would these work even though it states they must be run with the DIS system:

Would I only need 2 of those because they are for dual coil ignitions?

Thanks and sorry for the noob questions, lol.

 

In the case of the Tib, the "stock igniter" is in the ECU that you are removing. Yes, it's true, but in your case, there IS no igniter after removing the stock ECU.

What you want is either 2 1-channel igniters, or 1 2- (or more) channel igniter. The type of igniter should be a "dumb" igniter, or a "constant dwell" one.

In the case of what you sent me, MSD states it, "Must be used with MSD DIS-2 or DIS-4 series ignition box and coils." I'm assuming you don't have an MSD setup.

Haltech sells one that works very well, but it's a little bit more than that MSD setup you showed me.

I was tempted to use a GM HEI setup, but I couldn't definitively figure out what type of signal to feed it. Here's the rub: If you over-dwell a coil and igniter, they blow on you. Bad times, obviously, so it's important to setup the EMS to feed it the correct signal.

 

did I miss price somewhere in the thread?

 

Price is dependant on what you want and could vary quite a bit. The price will vary with how much wire, what features, if you want me to source sensors for you, if you have an ECU to use, etc. tdonnel and I worked out a price.

If you want a short enough loom with stock features and you have your own sensors and ECU, it's 350 base. Extra would be added for mapping and testing if you so wanted.

 

All of the stock sensors should work with this right?

Other than the MAF of course.

 

Yup! Since your temp probe on the Beta 1 is separate from the MAF, you are golden. You will have to reuse this temp probe, as the EMS needs this information for air temperature.

If you are removing the MAF and associated plumbing, you might need a new place to mount the temp probe. When you go turbo, the closer to the inlet valve, the better. You have to at least put it downstream of any intercooler to sense intercooler heat soak and compensate for it.

This means you have a decision to make. Move the probe now or later, when you go turbo.

If you prefer to use a threaded probe, use this one for $15:

It is what I use for all my EMS customers. I use this one in my own EMS-powered car as well. I can include this in the harness for you if you would prefer. I'll purchase the sensor for you and add $15 plus shipping to the bill. You specify the wire length.

Does this make sense?

EDIT: Tommy reused his stock one, but we had an issue given how the stock probe attaches. We had a heck of a time figuring out how to get it to stay put in a pipe full of pressurized air. We finally wound up pounding a flat spot in the pipe and "attaching" it with RTV. So far, it's working, but I would have preferred to use a threaded sensor like above.

 

tell tommy he is a cheap whore and I will send him $15 to do it right...
and that I will see him in Aug. of 08.

..maybe sooner.

nice thread, btw. Enthalpy, you are the man. cool.gif

 

Thanks, man! I definitely try to help out! cool.gif
