Saturday, I ran my 2.4l auto at No Problem Raceway in Louisiana. A few of us from the forum had a mini-meet there, just to have some fun - nothing serious.

The track conditions were horrible. They had to stop the races a couple times due to rain.
Needless to say, on a dry track, we all could have done much better.

My first run was my best, though it was the very first time I launched a front wheel drive car at a track. I ran a 15.350 @87.45mph with a 2.3 60ft time. As track conditions deteriorated, everyones times got even worse. Thanks to Tune Time's great TCM tune, I roasted my tires each time my auto shifted into in 2nd gear on this wet track. It normally chirps second in dry conditions.

I think my trap speed was a little low compared to my ET. Maybe this is due to my lack of traction, but I think it could be from me getting some KR and the subsequent loss of timing. I don't have a wideband, but after every run I got a P0171 (lean) CEL.

I think my e-rams are pushing a little too much air at WOT for my maf to keep up, as I don't get this CEL during normal driving. What do you guys think?

Heres the slip for you doubters:

 

I don't know nothing about the e-rams. Just gonna congradulate you on good showing at the track. Considering the shitty track conditions, I say you did pretty good.

 

i dont mean to rag here, but i would advise that you take the e-rams out. those things really wont do much of anything for you if they dont work against you and you risk something breaking and being sucked up... you may even be restricting air with these as your motor already "sucks" air and these may just be blocking flow by not compressing enough air....that would lead to a cel.

 

Good work on putting up some hard numbers for us 2.4L guys. What would you say the total price tag on your mods are? Plus how much did your tune run?

I've been thinking about running my car. There is enough interest in this area that I could run it stock races only. But the temptation to add things to my car is killing me.

 

I got the same code when I put a cone on my stock air box (relocated the MAF) Your pulling in too much air from what i can tell. What the hell is E-Rams?

 

If the e-rams were restricting my air flow, wouldn't the car be running rich? When I got my Wester's tune, I asked them to add more fuel to my WOT fuel map. I guess they didn't add quite enough fuel.

I know some people are dead set against the idea of electric supercharging - and that's cool, to each his own. But I can't see where two 6 bladed metal turbines spinning 25,000rpm, trying to force 800cfm into an engine that is trying to use less than 300cfm is going to hurt performance. Maybe if you were saying that the static blades at 3/4 throttle were hurting performance - that might be a valid concern. However the static blades are in a 4" housing that flows as much air as a 3.1" unobstructed tube, so I don't see the problem.

Now if you were arguing that the air is too turbulent flowing by the MAF for it to adjust the fuel mixture properly, (because the e-rams are not installed or positioned properly) then you might have a point for me to consider. The e-rams don't really function any differently than a big hood scoop does at say 200+mph. The e-rams just do it off the line.

What if a turbocharger's bearings failed? I actually had it happen to me once. There is the same danger of sucking bits of metal into your engine. Plus there's no safety screen on a turbo or SC like there is on the e-rams to catch debris from entering your engine. I was lucky and when the bearings went our on my Rajay turbo - nothing entered my engine, but some aren't as lucky. It's a chance you take.

 

The e-rams.....................$600
The Westers tune............$400
CA header......................$200
CA B-Pipe.......................$190 (I think - group buy)
Corsa Touring Catback.....$775
Injen..............................$225
Total............................$2,190

 

I'm thinking your getting this light because you MAF isnt turned for this e-ram. Im not so sure your mail-order tuner will be able to correct this, you'll need someone with hptuners to diagnose the issue since your not really "tuned" for the e-ram.

Also, do you have a switch for this e-ram or is it on all the time? the sudden change in pressure from using a switch could be the issue as well. Maf's fueling are somewhat self correcting, however completely changing everything would freak it out.

 

The e-rams draw 120amps, so they only run at WOT. I've got a nitrous type microswitch under the gas pedal, so they only come on when it's floored.

Do you know if I have to have my ECM "unlocked" after the Wester's tune to adjust the a/f maps locally, or can I just bring it down to a local shop and get it dyno tuned.
