T1 SMEC ATX & MTX / 1989 / 2.5 liter / 8valve / 2-3bar / All inj types - Collection

Here are all of my 2.5 T1 SMEC Base Cals...

The cals that do not say "3-bar" in the title are 2-bar cals. Some had asked for the CE Flash and Switchable boost in a 2-bar cal.

All of these have the CE Flash mod and Switchable boost available (can be enabled or disabled if you desire).

There is also an option to enable the Charge Temp Sensor.

These are base cals. They are stock cals except for being scaled for 3-bar MAP and +20 or +40 injectors. They will work well on a stock engine, but will obviously need to be adjusted for heavy mods.

The .zip includes the binary and the D-Cal table file.

Updated:

Added 2-step staging limiter. Both switch and speed de-activated. Either one will de-activate the staging limiter. The staging limiter is setup the same as the normal rev limiter (with a fuel off setpoint and a fuel on setpoint). If you have any questions about setting this up, please shoot me a PM.

Awesome job!~!!!!!

What's normal to see with the CEL mod turned on? I'm running the 2 bar 33pph injector 5spd cal. I don't have an OTC to see if the cal is pulling timing or not, but the CEL will come on sometimes at partial throttle, and always at WOT. I'm running a 2.5L With a TII garret turbo, and a stock TII intercooler. The car is an 88 Lebaron swapped to a 4 wire O2 sensor and 5spd trans. Ive tried 92 octane fuel with half a bottle of 104 octane booster, but no difference was noted with when the CEL comes on. I also replaced the knock sensor and the fuel filter to make sure I didn't have any other problems.

Thanks,

I also want to add that I'm only running about 6 psi of boost with the wastegate hooked directly to manifold pressure.

are you sure you have the 33lb injectors? older stuff had 27lb just incase they got mixed up somehow.

+1 to what brian said, if you are using the original 88 T1 intake and injectors they are 27's. The first blow through T1 in 88 came with 27 lb injectors, and then they upgraded to 33's in 89' for the 2.5L.
Could you possibly get the part # from the injectors, and/or confirm they are from the original 88 T1 engine?
Do you have an Air/fuel gauge???

[TopDollar69]

Nope, they are the injectors from my 90 Spirit that the engine came out of. The engine always pulled hard in the spirit, and I drove it with these injectors for 20k miles or so. Is it not normal to be seeing the CEL come on this much? I forgot to mention the car has a digital dash, could the CEL be latching when it would normaly only flicker on an analog gauge car?

[moparzrule]

Do you have an A/F gauge and/or EGT gauge?
Is your ignition timing set properly? Cam timing?

Did you check codes to make sure the CEL isn't coming on for a reason other than knock?

[TopDollar69]

The car is only showing codes 12 and 55, so everything is good there. It was throwing the code for the charge temp sensor, but that was because I didn't have it hooked up yet. I fixed that last week, so now I only have the normal codes. I do not have an egt or AF gauge. The car is all stock more or less so I really don't see the need for them. I guess the intercooler on a non intercooled cal might be throwing things off a bit, but enough to cause a problem? I think I might just have to break down and buy a scanner to see if it is pulling any timing. Thanks for all the input guys.

did you yourself turn the CEL mod on. when i downloaded this cal (though it was the 3bar +40 one) the CEL flash was turned off by default. Moparzrule pointed that out to me.

maybe its something else. just a thought.

Brian

[moparzrule]

I would atleast hook up an A/F gauge just to see what is going on, easy and cheap enough even if you had to borrow a gauge.
But you didn't mention anything about cam or ignition timing? Either of those can make knock appear. Are you positive they are both correct?
Intercooled or non-intercooled wouldn't do anything at 6 PSI.

[TopDollar69]

The cam timing is dead on, the ignition timing is set at 12 degrees. I set the distributer timing the correct way. The CEL mod is turned on, and so is the intake charge temp sensor. I checked all the options in D cal. They were turned on when I downloaded the cal. Now that the 104 has run through the system the CEL hasn't come on at partial throttle at all, but it still does at WOT.

[moparzrule]

Well then the cal must have too a little much timing for octane boost to make a difference. But the fact that 104 octane boost turned the CEL off any at all means the timing is close but just a hair too much. 104 boosts it 10 points, which makes 92 octane 93 octane. Back off slightly on the part throttle timing above 0 PSI and a little more at WOT.
Can you post what the timing is at what PSI level at every one of the points from your WOT table?

[Aries_Turbo]

id check the fuel injector part numbers and the A/F ratio before i changed anything in the cal. DONT tune for an improper combo, fix the mechanical issues first. check the fuel pressure too. it shouldnt be knocking at 6psi.

Brian

[moparzrule]

Yeah thats true, thats why I wanted to know what his timing points were set at first. He said the plugs looked good so that kinda rules out one injector being clogged and not flowing enough or something like that. Plus the 104 octane helped, that means it has to be a timing issue.

[TopDollar69]

I will pull the injectors and confirm the part numbers. I may also try retarding the timing somewhat to see if I can get the CEL to stop coming on at WOT.

Thanks

[Aries_Turbo]

could be an overactive knock sensor too. try a spare if you have one.

is the motor overall quiet?

Brian

[moparzrule]

He said he replaced the knock sensor....

[TopDollar69]

The engine is pretty quite except in the morning when its super cold on start up.
