my new "Wait4me performance" PCM...

[phunk]

great thread guys.

its awesome of you to post your comparison track times. thank you.

[99,4.3vortec]

yea great thread..i think im getting rid of the hypertech now and going to go with this...so i just call their number and they will set it up for me or what?

[draginlow]

e-mail them or call
they are a good at telling you every thing and they will work with you
and they are fast

[99,4.3vortec]

thanks...will do

[xxosiris9xx]

yeah im slightly tempted to ditch the hypertech for this...id ditch the hypertech outright but i like the no speed limiter and bit of extra power

[Toadz]

I was taking a look at the Wait4MePerformance website and they say you can send them your wiring harness and computer to be modified. Does anyone know off hand if they'd be able to modify my harness to work with my '91 4.3 going into my '96 Sonoma? I'll be giving them a call tomorrow to find out for sure.

X2 on the manual info

can i get rid of the egr from the ecm ? will it make a differance in the way it runs and performs ?

I was thinking the same thing. just shut it off completly. I don't think I have to worry about it at inspection time b/c they only read the codes no dyno.

[travy]

If you keep your trucks oil and gas clean then i don't see much of an improvement of taking the egr off. But you can plate it up if you want.

[Mikz86TA]

Im waiting on a response from Jessie at W4M....about the TM on a manual. As well as his input on what I want too. Hopefully Ill get a PCM tune soon too =)

[s-10hater]

yeah i don't need to dyno my truck either,thats why i was thinking of getting rid of the egr.plus a lot of people that i talk to say that the egr is a problem with the newer trucks(95 and up).just figured i would solve the problem before it happens.

somebody done this,any thoughts ?

I think the EGR becomes a problem in all vehicles after a certain amount of time, no matter how clean you keep your gas and oil.

[TECHRF]

nothing good can come from putting carbon filled exhaust into the intake except to make you mechanic $$$$$.

[phunk]

today i overnighted my PCM to W4M. I have been in contact with them via email but so far I have not been able to get them on the phone. Hope all goes well. It says on their website that they can occasionally do same day service... so I am crossing my fingers that they call me tomorrow when they get it and are able to overnight it back to me. If so, I will post my before/after dyno numbers to coincide with my baseline dyno thread I started here: http://www.s10forum.com/forum/f107/b...03-zr2-309285/

[phunk]

Update, I just talked to someone at W4M. He said he believes he will be able to ship it back to me tomorrow. Nice! Dyno results on friday for sure.

[j894]

sounds good

[Mikz86TA]

Ive been e-mailing Jesse/Hannah at W4M for a couple days. They have been very informative and quick to reply. I asked about the TM on a manual, and they said there wasnt any. But studying the JET programmers real-time data info, the timing gets cut on shifts. The more the throttle is open the more it cuts. Im to the point mod-wise, that a custom tune from them will be best for me. I trust their judgement and will be doing one soon.

[Crew Cab Sonoma]

my latest tankful has netted a rather impressive 18.2 mpg.
a new best for my truck... previous in-town best was 16.9.

[Toadz]

Is their e-mail the same as their PayPal?

[Mikz86TA]

HannahBubb@Yahoo.com I believe it is

[phunk]

got my PCM back today and put it in.

my perspective is warped since I have been driving my car daily for the last few days, and its lightyears faster than this truck will ever be. But I personally cannot feel the difference right now. Perhaps its hard to differentiate between painfully slow and really slow without hard numbers.

Right now I am trying to decide if I feel like driving to work today to put it on the dyno and see what it did, or if I want to just wait until tomorrow.

[phunk]

OK, at the shop now just finished strapping it down. Gonna smoke one and let it cool off for a minute.

After driving the truck more I am convinced that the off idle power to at least 2500rpm is better... the truck takes off much better from stop lights and doesn't SEEM like it takes as much throttle to keep it going. Its still possible its all in my head, but I want to describe what I think I feel as the truck feels lighter, less like someone dropped anchor and im dragging it down the road.

I am not so sure if it feels any faster at full throttle and higher RPM. We will find out in about 15 min for sure. I will post the results when I get home in a couple hours. Peace

[phunk]

OK... gonna let it cool down more. The first run was about 5rwhp gain thru the entire powerband. During the shifts, with the torque management and line pressure adjustments he made, the gains are 50rwhp during those shifting spikes.

The speed limiter is gone, I took it up to 125mph and even on the dyno with no wind resistance that was really pushing the truck. Pretty sad, hahaha.

That first run got the truck super hot and the next run was terrible cause of the heat. I have 30 min till everyone is leaving here, so I am gonna let it cool down that entire time and see if I cant get a better pull. Ill put up the graphs later.

While so far the power isnt making me too excited, the way the truck drives is still well worth the $$$ in improvement. When I lay out the graph by TIME in seconds rather than engine speed or wheel speed, I can see that its reaching speeds quicker, I will post that evidence tonight as well.

[Mikz86TA]

What are your actual dyno numbers? And what were they B4? Actual picture of the graph is best if you could please. THX Oh, RU a X or W VIN?

[phunk]

I am back home now. Let me collect the data and I will make a new thread with it.

[s-10hater]

so should i have jesse take the egr code out of my new pcm ? i just never liked having hot cabon filled gas recurculated into my intake. and when i get it take out i guess i just unplug the egr.

[Crew Cab Sonoma]

ok, the latest fillup has netted 18.9 mpg from basically the same driving conditions as usual....

[Crew Cab Sonoma]

s-10hater, sorry for the delayed response, but by all means, have him remove the EGR code, then disconnect and/or remove the EGR if you like.

[Mikz86TA]

any more news/info from any users?? I had a setback on getting mine so far. But Im still working in it =)

[phunk]

i never measure it, but i am almost positive my MPG has gone up a bit. I drive a ton, and always noticed how poor my mileage was. The last few tanks I look at the gauge and its always up a little more than i expected.

I am still glad I got it. You can feel the difference during part throttle driving. Full throttle isnt a noticably quicker aside from the more aggressive shifts.

i just bought a cam, so after i swap that in and dyno again i may or may not have to send this PCM back to have the shift points raised, depending on if the cam is still in its powerband when it shifts at this stock shift point.

they can raise the shift points, right?

i have a feeling that after i put in my HD2 shift kit, and with the torque management adjustments W4M did, this baby is gonna really slam gears hard under full throttle. im pumped. I dont do auto trans, so i gotta make the appointment for shift kit install in the next week or two.

[wotgtp]

damn i got to get this.

[Mikz86TA]

If you get a cam, I would get it updated for that definately. Never mind the shif points, just the new cam profile probably could benefit from a tune
