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Even the ath7584 is obsolete?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?

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

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.

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 :)

Thank you!

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.

Okay Thanks!

Hey guys,

Here is an update,

I did a full brake job on the car and replaced the v-belts. Also did the ignition module upgrade to the 86-87 setup, man what a difference!!

I have the car running now, pretty smooth idle, took it for a drive with my son and it has some "get up and go".

I bought an ECM for $75, from ebay out of an 86 olds , 1227148.

Now I went on to the the TurboTweak site and it states on there that Eric will not be shipping international as some packaged recently have gone missing. So i guess I will wait to get a chip burnt for my setup.

My question is if I get a street chip and 60lb injectors, can the chip be tuned to run the injectors at a lower rate until I get the cars turbo upgraded, hopefully to a TA33C (very hard to locate).

Also i would need the lt1 or ls1 MAF and a Maf rranslator correct?

Thanks for all your help so far guys!!!

I thought they ran okay without the calpac but Eric is the guy for the absolute answer.

I think the problem with the calpac was that when larger injectors were used, the engine would be flooded badly with fuel.  Calpac required tps and ignition pulses from the module to let the engine barely run.  If the cal pac was not in the computer, the car would not start.  I think Eric removed the requirement of having one installed but, like I said, ask Eric to get the straight info.  He's a very nice guy.

Okay, I will send him a message on his site.

Thank you

Stock ECM's are a dime a dozen. Go to my Youtube channel. I show how to mod it for PL.

You are right, they are all over Ebay.....are the ECM #1227148 from the 86/87 Century, or Oldsmobile,  98, all an option for the GN ECM swap?? Or does the ECM have to be from GN/Regal?

Thanks

Reading from Erics forum, you can swap in an 86-87 ECM and use Powerlogger. He also recommends swapping out to an LT1 MAF and Translator. And I'd grab his street chip, if the car doesn't have one. Stock injectors are 28 lb.

Okay Thank you fir the info,

I was actually thinking of ordering the 37lb injectors from racetronix, but am still unsure. The 86-87 ECM idea is a great idea as well.....man i,m a bit confused. Are there 86-87 ECM's being sold on the site often?

Hey guys,

Some good news........i lightly tapped the injectors on the Drivers side with an extension and hammer and tried starting the car up and right away it sounded like it was trying to fire up, I cranked it over about a dozen times and than tapped the injectors and than 2 on the passenger side under the turbo and it actually started up for a few seconds. Wish you could have seen the smile on my face.....espec ially on my kids faces.....my son is 11 and is a total car fanatic.  He already told his sister that he is going to drive the car to grad, and that she can drive my 442.

I am thinking I am going to take the turbo off and have it looked over and possibly rebuilt, and try to find a local shop here to see if i am able to get the injectors cleaned. I may just order a set of replacements.

Can anyone tell me if I should keep the stock injectors or get some higher lb/hr injectors??? Also does anyone have the specs of the stock injectors for an 85?

Thanks alot guys.

Are the injectors spraying fuel?

Totally slipped my mind to even check the injectors.  What is the easiest way to check? Take themnoff the manifold whole still plugged into the harness? Or unplug them and get them tested at a shop?

Thanks

Hi everyone,

Okay here goes. I picked up my 85 Grand National after sitting for over 16 years.

I knew the gas tank and fuel lines needed to either get replaced or cleaned out. So i went ahead and replaced the Gas tank and fuel sender/pump with the Spectra replacements. I cleaned out the fuel line and return lines as well and replaced the fuel filter. I primed and it and got all the air out of the system and had fresh clean fuel at the rails and shrader valve.

After doing all this the car still did not fire up, just cranked and turned over.

So I decided to do a spark plug and spark plug wire replacement along with an oil filter and oil change. I even took the coil pack off and did the ohm meter test and all the ohms were between 11.2 - 11.6. I watched a YouTube video that a member on the site did where he tested the coil pack with the ohm meter and thats what I did. I just don't know if it would be different ohm numbers between a 85 and 87 GN.

After this the car still did not fire up....so i went ahead and changed out the O2 sensor  and air filter and cleaned out the MAF sensor with CRC Sensorcleen. And also changed out the Crank position sensor last night.

The car still hasn't fired up. I am a bit stumped on what to check or look for next.

I have ordered a 86-87 coil pack and ignition module along with the 86-87 hotwire adaptor from Caspers and will be upgrading the i85 gnition system next.

Also I have checked all the fuses and they all are in working order, I also hooked up a OBD1 reader and did not see any error codes at all.

I notice the oil/choke light is almost always lit up on the dash along with the check engine light when I am trying to fire it up.

Anyone know what else I am missing? Or take a look at to narrow this issue down?

Thanks a bunch guys.
