ACV / Haltech / Assembled Vehicle question
Originally on haltech forum - maybe will be better here. Sorry for the duplication. Anyway, help please.....
As a background I am scratch-building a lotus 7 look-alike with a 13b-RE JDM engine. (picture of car can be seen attached to my first post last night in the haltech section - she's not an RX but I love her anyway). It will be titled as an "assembled" vehicle here in Texas this means the car will have to pass a full safety inspection - including emissions both sniff and visual (I think) at a designated safety inspection location. (Conroe?) With luck it should be ready for this in a couple of months time. Chassis / body / suspension etc done but for finishing.
The car will have no AC or PS or roof or any other fancy stuff... and I have already converted to full non-sequential (for simplicity) and will be using a manual boost control set-up. The "Rats nest" and solenoids are all history. The car will only weigh around 1200 lbs so I will not lack performance I am sure.
The RE engine does not have EGR as it is a JDM (Thanks Gary!). I am using a side pipe exhaust consisting of a small SS cat and muffler. Also, PCV is no problem as I can figure that out on my own along with the charcoal cannister deal (although the purge is history!).
I understand from previous posts that I can use one of the Haltec PWM outputs to switch the airpump clutch on at idle and off at say 3500 RPM I guess, but I am confused as to how to make the Haltech control the other ACV functions, and indeed which I need to use and when. I guess I can use the other PWM outputs in a similar way as I should have some available. I have an E6K.
Here goes with the questions.........What ACV bits (i.e. Port, Split, Relief?) do I need to have operating when, and under what engine conditions. I think i need the port air (to manifold) to work at idle and the split air (under load?) up to 3500 RPM but I'm not sure........On the RE's ACV there are two 1 pipes . I guess one is from the Air pump and one is relief. There is just one electrical solenoid valve in the body of the RE's ACV that I think controls the split air, and there is also one vacuum inlet that closes the lower one of the two 1 pipes when under vacuum. I think this does the relieving.???
Hope this is clear to someone with some savvy! I checked but couldn't find much in the archives. ..Thanks in advance for any help
