WTB Chip

[95SleeperAcheiva]

On the forum here I found a part # for an ECU. 1227730.

Motor is a 2004 3400 from an alero, transmission is a stock 4T60E from a 95 Acheiva. No emissions, no limiters. This car will be track only. I already had it running on the stock 95 obd 1.5 comp and pulled 16.00 sec 1/4 mile.

If this is the comp to buy ($80, reman-no prom) What prom do I look for to go with your chip? Also I plan on swapping to a W-41 Getrag mid-season. When I do that do I need a differant prom then to go with my 2nd chip from you?

I'm ready to order now, opening day is April 24th, so I need it by then, prefer by April 22nd so I can make test and tune.

thx

damn, sorry about this but I didn't see your thread until now. You need a 9396 ecm from a 91-93 3.4 DOHC or a 93 3.1 w body to control the transmission. I am not sure about a 3400 swap chip for a 4T60-E though. What I have is for a 5 speed and I am also not sure about the transmission control since the 94+ 4T60-E had some changes done to it.

if ben cant do it i probably can, i'm working on the obd1.5 to obd1 conversion now.

I'll hunt for the comp this thursday. Is it possible to burn in the stock transmission values for the 95 acheiva?

And...if I may just whine for a moment....

I want 1.6 rockers for my '03 3400, whaaaa!

[robertisaar]

if you could somehow decipher them from the bin, sure. i just use the 3.4 values and adjust to my liking. the 3.1 version shifts way too soon for anything other than a LH0.

[SappySE107]

Stock are 1.6 on a 3400. I have no idea what the stock values are for your car but it would be easier to adjust what the stock tables are. They are MPH based, not RPM so that makes it more difficult to setup shift points.

robertisaar, do keep us updated on the progress!

calm down isaachayes, i've been waiting on 1 part for over a month(the black pcm plug(if i really needed it, i could hack the original PCM apart and use it)) and its supposed to be here may 15th. when it gets here all i have to do is yank the old PCM, plug in the harness adapter, install new PCM, and its good to go. then i'll see what problems might pop up. and Ben, i came across that issue as well, then thought of this:

just go to wikipedia(or some other trusted source) to find the gear ratios of the tranny you're using, and you can set the WOT shifts pefectly, then just scale them down for lighter throttle. and if you notice it shifts too early or too late for your liking, make a note of it, adjust and try again.

[95SleeperAcheiva]

Am I being a hassle? If so I apologize.

I'll get ya the gear ratio, i found it a few days ago.

So where can I get one of these 1.5 to obd 1 chip. I wanna tune !!

patience, i'm still waiting on 1 part so i can get it hooked up and tested, but i do have a good feeling about it, so by the middle of may, send me a PM or something or look around the sire for a guide.

obviously you'll need a chip, which i can do that as well, since the WOT-Tech doesn't do them(for this application) and i'm not trying to steal sales away from the store(since i'm sure donations from it help keep it alive).

[Iyyob]

wonder how much farther is mid may ....

[robertisaar]

the part is supposed to ship FedEx Ground on the 15th.... trust me i've been waiting since late march, its killer.

[Iyyob]

so any updates

I can tell you that this is killing me with the shifting. So, I'm working on the manual automatic currently. Provided I'm doing all the shifting, does that mean I get the ecu ben suggested, do the obd 1 swap, get his chip, and neither Ben nor I will have to worry about the ECU operating the trans?
