Gene's 2.2 LAP Supercharger Build
So, while studying how I am going to handle the IAT2 conversion today, I decided to handle it differently.
Instead of cutting wire at MAF I am going to take out the pin/wire at the ECU and put in new wire and new pin. I had the right pin at work and the right crimp and release tool to go with it.
This would also make it able to be done without having to remove the wheel liner, etc if you weren't going to do the intake at the same time.
I'm still going to do the intake but I'm saying that if there is anything wrong I can simply take out the pin and wire that I installed and put the old pin back in and reinstall old MAP sensor. I doubt I will need to go backwards.
The pin on my car is #58 for the IAT. I will post up some info either over or after the weekend.

lol i'd rather know the temp of my engine on the main display than the temp of air going into it from manifold.
i'm asuming you're going to put in some kind of gauge for engine coolant temp? thats something that shouldn't be overlooked.

lolHe's just saying instead of cutting wires at the actual MAF sensor, he's going to re-pin the wires where they lead at the ECM to make it look mor professional.
Ok, so yesterday was a bit long and hot here, lol.
After viewing the loom and all coming from the ECU it was apparent that with the way it was setup it would be better to cut the wire at the MAF.
The Injen intake isn't that hard to install, but even with being very gentle installing and even with wrapping it up in painters tape trying not to scratch it, it got scratched. I was pissed, lol.
And Injen sends you this little seal to go around the opening that goes down into the wheel well so that the metal doesn't rub a hole in the pipe and go into the SC. Twice I had the intake mounted up and then the seal moved (probably while I was pushing the pipe through). The last time it happened I had the MAF sensor on the pipe and everything and I was so mad, hot and tired I broke the MAF connector. I had already messed it up previously when I was not supercharged, oh well.
At any rate, the intake is installed and I will have to get a new MAF connector on Monday. I'm just going to take the pins out of the old connector body and put them into the new connector body.
Previous to installing the intake it took me a couple of hours to run the wire for the IAT2's over to the intake manifold. I basically had to cut off all of the electrical tape and tear apart the whole loom again just to run this wire and make it look professional.
It was a long and tiring job. It was like 90 degrees here yesterday and high humidity, lol.
I touched up the pipe with some of my black GM touch-up paint and it looks fine. The IAT2 wire is spliced into the MAF already. My friend is going to come over probably tomorrow and we'll install the LSJ 2.5 bar MAP and connect the IAT2 wire. I will make sure the IAT2 works before I put the wheel liner back in and the wheel on. I can do the 2.5 bar MAP install myself but he has a little butane torch especially for heat shrinking the connectors and melting the solder inside the connectors so I'll just let him do it.
So I'm about 3/4 finished with the project.

Ok, today I got the new MAF connector (I broke mine the other day remember) and my friend stopped over and did the LSJ 2.5 MAP connector conversion for me. I got in and started it up and it was reading something like 65,000 for the IAT2 temp, lol. So, luckily I didn't put the wheel well liner back in as I made a stupid mistake. I connected the newly ran wire from the MAP the MAF sensor. The wire should have been connected to the wire that originally went to the MAF, from the ECU. Luckily I had male and female weatherpack connectors on both so I just added another female onto the old MAF IAT wire and connected them.
I started it back up and I had IAT2's! I then had to reinstall the wheel well liner and the wheel and my friend cleaned up the wiring, etc and buttoned it up. It was late and wet outside so I didn't take it for a ride or anything.
All I can say is... I can hear whine...pretty impressive supercharger whine now when I hit the throttle. I can't wait to hear what it sounds like on the open road.
I'll have to monitor my IAT2's and see if I am going to drop a pulley size or not. I will also have to do a couple more runs and record on the Interceptor and see if I got any horsepower gains from the Injen cold air intake.

Hmm...perhaps I'll consider doing this in the future - but I don't have an interceptor that would allow me to read IAT2s...
...but yeah - having a big open filter makes for a loud ass supercharger, haha.

Well, it's not only the open filter, the Injen is then 3" pipe up to the short TB hose. It gives 16HP increase, but I'll have to see for myself.
Sorry guys. I tried to get on last night and this site was fugged.
I did some testing the previous week with the IAT1 on the Interceptor so I could compare to the IAT2's.
Last week we have been in the mid to high 90's and my IAT1 would be 10+ or more degrees at cruising and one time I was stuck in traffic my IAT1 was 122 and the temp outside was around 90... so even the IAT1 can get pretty warm.
With that said, I read on here that the IAT2's should be +20 or +30 of the IAT1 temp. Yesterday wasn't as hot and I was seeing anywhere from +15 to +25 of the outside temp. I cannot compare to the IAT1 since it isn't hooked up any longer.
This morning I was running +15 to + 25 again. On the way home it was the mid 90's again and humidity was high and I was running +20 to +29. In traffic.. sitting, I was hitting +31 but that would only be for a second.
It seems as if the front mount heat exchanges, ZZP in my case, hold up much better than the stock since they are in front catching the cool air. It was like 79 or 80 on the way to work this morning and I was hovering at 100 for a while, IAT2's, so I'm doing pretty good with the 2.9 pulley and no other cooling mods.
I haven't done a 1st through 3rd gear run as the place where I can do it this morning had cops there and I was followed in my good spot on the way home by a cop, lol, so I couldn't open her up and find out what the IAT2's are after I do a run.
I certainly have enough cooling at the moment for a 2.8. I believe after I get home after a quick getaway this weekend that I will order the 2.8 and then have Vince tune again when he gets back from vacation.
I'm anxious to do another 1st through 3rd gear run and see how much HP my Interceptor says I have now.
But all in all... yes.... the IAT2 conversion works flawlessly.

Vince left today and coming back 8/31.
Sent you an email last night with the price on the connector and the connector wiring diagram.
Well, this morning I had my first chance to do a WOT run, lol and it didn't go well. It appears with the different MAP that my tune is messed up. Vince said it would need retuned, but it was not doing power enrichment properly and it was doing some serious timing retard or something, lol.
I did notice two things. Previous to the CAI and the 2.5 bar MAP I was only able to hit 14.5 PSI. I thought I saw 15 once, but didn't after that, so I'll stick to the 14.5.
This morning I noticed it went right past 15 and was steadily on 16 and that car was acting up, like not pulling hard, so I kind of got out of it. That is when I noticed that the power enrichment wasn't working properly. I am getting some, but not like it was previous to the 2.5 bar MAP.
The whine got really loud though, at WOT, so that was pretty neat.
If after Vince tunes me again and it is running properly and if I hit 16PSI or greater again then I am finished with the pulleys. I am not going to 2.8 on this thing lol. I would have like 18 PSI and my car would go boom probably.
I would say if my boost increased then my old MAP must have been leaking slightly and leaking out my boost a little.
At the same time, I was recording IAT2 and HP on my Interceptor. I checked the HP when I got to work and it said 204 MAX and it felt about right because it was a dog. It is acting up with the new MAP in there.
It robbed me of about 95 HP or so.
I will have to drive it like an old man... grandpap... until Vince gets back from vacation.

Haha - yeah, it's amazing what a CAI can do for whine - I can't wait till I can afford one...it'll be even louder!
Sucks to hear you have to get it retuned - especially with the vacation they're all on...
Man - I'm paranoid running my car at 14psi...****, 16? God...

lol at 84 degs i hit 16 psi. (2 am)
it does well.
It is now idling most of the time at 1500 RPM's... wtf, this sucks. Not only is it idling at 1500 most of the time, it is also coming down slowly from RPM's when I shift so it is irritating as well.
Can I see the timing on my Interceptor or am I looking for retard?
It has a serious case of the not fun to drives anymore. lol.
I need V I N C E
Oh yeah... also trying to figure something else out.
I have ambient temp on my Interceptor and I cannot figure out where the data is coming from. My IAT1 is not connected or no longer working... it is not the same temp as the outside air temperature so where the hell is the info coming from?
