4 cyl - the votes are in!

[Chris@HPTuners]

Well, I am a little late, but here is the start of the 2002+ Alero 2.2L DOHC tuners swamping you. Just because we have been outcasted by the shut down of Olds doesn't mean we can't run with the best of them. Here is to making a 2.2L DOHC in a 3400lb car (me included 8)) beat a v-8 in the quarter.

all standard 4cyl code has a "faster than v8" fuel cutoff to prevent such a circumstance arising :P

it cannot be changed due to religious reasons...

Thats some funny sh*t Chris.

Anywasyatleast it looks like by the charts posted the 2.2/2200 OHV engine will get some much needed tuner love. My turbo engine thanks you and keep up the good work.

Im ready to order as soon as you say its ready.

[IamQBE]

so whats the update here?

when are these coming?

[Chris@HPTuners]

still in development.

hoping to start beta within a few weeks and then release maybe 4-6 weeks after that.

Chris: PLEASE LET ME HELP BETA! I need this software to tune my turbo eco so i can run more than 15PSI Plus i have lots of dyno access as needed to toy around with thise setup.

I dunno if the stock PCM can handle boost, from what i've seen so far it either runs Speed Density (MAP) or Alpha-N (TPS) fueling. The software will only allow you to tune within the PCMs own limitations.

When we get a little closer to beta time i will post.

I am still new to tuning, but getting better.

But, I already have hptuners for my '00 v6 Camaro.

My live in girlfriend has a stock '00 Z24, 2.4L Cavalier, if you are looking for a beta tester that already has the hardware(unless you need something new)

Don't worry, you won't be losing a potential sale, not really going to mod the car much, and likely wouldn't buy hptuners for it anyways.(that money is going to my car ) but I like to fiddle, and helping others

[MustangEater82]

Ive got a question, what about the 96 2.2 ohv. the motor is the same as the 97 but is there a differance in the pcm that would make this non-compatale? assuming if everything went through for that motor. and if there is a big difference do you know if the pcm would be interchangable with a newer one that would be compatable? Thanks

not sure, may have to ask cavalier gurus... but v6 f-bodies have a similar issue. 95-96, can swap in a 97 PCM and use hptuners.

but not sure if the same will work for you.

let me use it then, I am boosted 9 psi on an eco with NO ecu problems what so ever... it loves boost... if you need a boosted ecotec to tune beta let me know as I have dyno access as well..

oh yeah btw... if the ecu sees boost it throws a map sensor code and then you run check valves, I have not had that problem yet

[hypsy]

i havent gotten any codes do to the boost yet...except the system rich code but that doesnt bother me any

[IamQBE]

I havent even gotten that, I used my wideband and boost to get great a/f's right now but I need more

[black98s10]

Hey Chris, it's Phil if you need someone to do Beta on S-10's I will be willing to help out. I have a laptop ready to go.

[IamQBE]

any news? getting ansy, i wanna test this I need tuning capabilities soon.. I wanna hit 14 psi but cant without this..

[hypsy]

why cant you? im running 16PSI at the track now just fine. dont know why you cant but im having 0 issues with the car doing those numbers

[boostedeco]

^^^ what fuel system mods are you running out of curiosity

[hypsy]

330cc injectors, 6:1 Begi FMU, second fuel pump inline

[IamQBE]

I dont have a second fuel pump

[IamQBE]

btw how is this coming along?

Small Update

- base definition is done, now just populating calibrations. The 4cyl requires a number of changes to our editor due to different data structures within the PCM compared to the V8's & V6's. This complexity was unexpected.

- my goal was to have something out before SEMA but time is running out and extra hardware delays due to the Superchips partnership have delayed v2.0 further. The 4cyl requires the new hardware so this is gating things a bit at the moment.

- in terms of parameters i'm aiming for around the same number of parameters as the V6 so i don't envisage too many issues. However there may be a few things that will need tweaking once we get into beta. Experience would show these are generally model specific quirks related to torque management, electronic throttle etc.

Best case, beta will start before SEMA (Nov), worst case sometime in Nov.
