I should have been more specific when I said stock ECM's are a dime a dozen. I meant ECM's for 86-87 TR's. E-mail Eric again and ask him about the ECM you purchased and the part number. That ECM may not work correctly for our cars. You can run any size injector you want...think Eric goes up to 160's. Ask him if you can run a Translator with the hot air car engines...if it's a go...then an LT1 will be fine.

Hi Steve,

I have emailed Eric, just waiting for a reply.

Thanks
If he does not, I will be happy to remail it to you if there is not one closer :)

1227148 should be the correct ECM for 86-87s.

Hi guys,

Finally got a response from Eric @TT. He is shipping to Canada now through UPS.

I met a guy through Kijiji selling a tonne of 87 Grand National Parts, and have got my hands on (2)87 GN ECM's with stock chips and a few performance Chips, a complete power antenna setup and powemaster Brake setup with accumulator, a complete Coil pack and Ignition module (which will be a backup) and a OEM 87 MAF, and a complete uncut 87 GN Harness( hopefully one day I can get my hands on 86-87 Intercooled motor setup).

Once I get the 87 ECM, MAF and IAT/MAT setup, I will be getting a street Chip burnt by Eric, he said it would be a good idea to put 60lb injectors innit as well, but he will tune it for my Hot Air setup.

Anyone know who is a reputable Turbo source that still has TA33C turbos for sale?

My main goal is to have my car Insured with Collector Plates  In BC and than hopefully start making it go fast.

Thanks for all your help guys.

Tell him to ship it USPS...not UPS. You'll get raped at the door by UPS for all their extra charges. They'll be more than the cost of the chip.

And forget about going fast.

Hi guys,

I got all my parts from a guy out in Charlottetown, I got (2) 87 ECM #1227148 with 3 chips, one of them looks to be the stock chip ATH7584,  but I got these 2 other chips, one is a turbo tweak chip and one looks to be a ADS Superchip. Just wonderingnif anyone could tell me a little bit more about these chips. I attached a couple of pictures as well.

I got a stock 87 MAF as well, I picked up a stock IAT/MAT SENSOR  as well,  i have a question now in regards to the placement of this sensor. Should it be between the MAF and Filter or between the MAF and the throttle body?

Once the ECM swap is done, I can hook up a scan master and powerlogger correct?

Thanks guys

The TT chip goes with stock 28 # injectors.  The chip has to match the injector size.  The other two chips are obsolete by today's standards and could be dangerous as they may have too much timing.

The IAT sensor normally goes between the filter and the maf.  Some times when spraying alky, we put it between the intercooler and the throttlebody with TT alky chips.  Some times, we don't :)

Don't count on the maf being any good if it is a factory one.  Most of them have long since died.  Your scantool will tell you.

Yes, SM, PL should work with the 86/87 ecms along with the rest of the conversion.

Thank.you so much!

My stock injectors are 28lbs, so the TT chip should work?

Even the ath7584 is obsolete? Is that not a stock chip?

Stock injectors are 28# - it should start with that chip - ask Eric if it'll work for your combo. 
By obsolete - Steve means don't use them with today's gasoline.

Contact Eric...he'll have a file of that chip and can tell you exactly what it was burned for. The number he needs is 8460...send him that pic of it as well. Chip is for 28 pound injectors and 91 octane. You'll need to know from Eric what size turbo it was burned for...as that's how he sets his fueling. If you have 28 pound injectors...yo u can plug that chip in and it'll work. No WOT shit tho...till you hear back from Eric. Throw the others in the garbage.

PL and SM will work with the 86-87 ECM...but double check with Eric.

Hey guys,

I had emailed Eric and got a reply back......

"The 8460 chip is for an all stock 86/87 car.  It may work ok on your 85 car, but the boost may be too high, unless you adjust it manually.  Also, that chip would need the IAT sensor, or it will throw a code.   The chips I make for the 85 car with the 86/87 ECM have the IAT disabled."

What is the difference in boost between the stock hot air 85 GN and the intercooled 86 87 GN??

Also how would you manually adjust boost on the hot air cars?

Thanks

From a personal standpoint, I'd have Eric burn a chip for exactly what you have. Changing head gaskets...suck s. Having a chip for exactly what you have and your goals eliminates fueling issues...as long as your fuel system is up to the task. Fueling is the number one thing guys don't pay attention too.
