I already downloaded a bin from here. I plan to use a EEPROM with a Moates adapter in the MEMCAL I just bought.

Good to know that the N/A engines used the same knock sensing. I wasn't sure that knock retard was used on the N/A engines.

The project is an electrically supercharged GM 2.8L V-6 (1986 Pontiac...

Found one on ebay - $101 (ouch!) but couldn't find an other option

Anyone know where I can find a memcal for this engine? gmeprom does not have one. The ECM is a 7727. The broadcast codes are: ASAN, ASMF, ATMJ, ATMK, AUAD, AUAF or AZRC. Trying to stay with an...

The four letter code is known as the broadcast code. The same PCM/ECM can run chips with different broadcast codes. The difference between broadcast codes is the way the data and operating...

New to boost and just realized that the 2 bar MAP signal will do the heavy lifting as far as fuel injector pulse width is concerned. So the boost multiplier is like an increase in VE while in boost...

1project2many,

Thanks for the reply and the links. Lots of good info.

Chilton say the 1X and 2x signals are necessary for fuel injector activation. I did elsewhere find info that says the...

I checked on availability of E85 here in central Texas and was surprised at how many stations carried it.

Well you learn something new every day. According to a Chilton I have, the ignition module is different for 92 and earlier vs 93 and later Quad 4. Both modules use a 7 notch reluctor integral to...

I have gone the less DIY route and use Tunercat. He does not list a definition file for Saturns but he may have one. I'll check

Tunercat has a $58 defintion file for 6 cylinders and a $58A...

I was hoping to go mass flow but the 1227749 with speed density look like it would work. The 4 cylinder is $58A. I downloaded the AKDB bin file. What variables need to be changed to make it work...

I browsed internet concerning unleaded AVGAS and it looks like 100 octane is just starting to come to market. The octane tests are different for AVGAS and MOGAS. One source said 100 octane AVGAS is...

I want to boost a Quad 4 engine with an Eaton M62 supercharger 10 psi of boost. What OBD I ECM/PCM would be compatible with MAF fuel control, 7X crank trigger and waste spark or coil on plug? Or...

Not how short of octane you are but can get 2 number of octane with an MMT containing additive for less than a dollar gallon of treated gas

I looked at the AXCN calibration for a 91 vette. There is no parameter related to PE delay. It looks like PE is enabled with TPS greater than 70.3 %. It does look like the AFR is very rich in PE...

If you want to tweak the PE air fuel ratio in search of more power then you will need to invest in a wide band O2 sensor (really an air fuel ratio sensor) otherwise you are flying blind.

You don't want to go anywhere close to 14.7:1. If you did run there at WOT there will probably be knock and the best case scenario is that the knock sensor would detects it and the PCM would pulls...

That injector is rated for 29.5 lbs/hr which might work. You might want to try Motor Man Fuel Injection Supply. I bought Bosch injectors for a 4.9L Cadillac from them and they were very reasonably...

Pontiac Fieros came with a 2.8L V-6 rated for 140 HP. GM later made a 3.4L V-6 using the same heads with similar intake and exhaust. This engine was rated for 160 HP. The displacement increased by...

I'd love to see some actual data from your existing engine to compare it to VE that DynaSIM estimates

C beam upgrade:

What I read is that the 92 and earlier ZF6's were German made and rated for 450 ft-lbs. GM licensed the design and in 1993 began making their own. They changed the design of some of the helical...

I just looked up specs on 1991 ZF6 transmission and it is rated for 450 ft-lbs. Not sure what the clutch and rear end is good for but doubt that the transmission is too weak unless you like to rev...

I watched a couple of the Richard Holdener videos and it is crazy how much peak torque the TPI intake makes. But the problem is that the OP is concerned about too much torque. So that leaves three...

I selected TPI from the drop down for intake type. Select dual plane, high flow intake with no other changes and you get 295 HP @ 5000 rpm and 360 ft-lbs @ 3500 rpm.

I have limited experience...
