computer chip recommendations
Having some issues with my '87 c4. check engine light comes on, so will the upshift light, will occasional stall. had a new computer put in but my mechanic tells me the chip is bad. Any recommendations on what chip to buy? are any of the cheaper ones(like performance chips direct) worth a shot or should I just suck it up and buy a hypertech?

I can burn you a new chip,you would need a memcal to start with.Look at this link. Here is a memcal for $80. I can insert a new chip inside that memcal for you,thus customizing and improving the tuning way beyond the limits of any Hypertech or aftermarket chip. http://www.ebay.com/itm/CORVETTE-ECM-COMPUTER-PROM-AUTO-TRANS-87-/121082984921?pt=Vintage_Car_Truck_Parts_Accessories&hash=item1c311bb9d9&vxp=mtrYou would first have to buy that person's memcal and send it to me for re-programming though.

I think I'm better!

Just kidding, any competent programmer is better than a Hypertech! It will be customized to your vehicle.

The best way I know of is to get it dyno tuned or with data logs. Any of the off shelf chips are a waste of money, IMO. I'm personally not a fan of tuning without seeing what the ECM is doing but it is acceptable if the programmer is experienced enough till you can get it to them.

I agree with you on this, so when I sell them I always tell them I'll give them a refund if it doesn't solve the problem. I've gotten follow up thank you's that it worked, so they must have faults. I've done this with both mass air, and speed density. I personally have never had one go bad, but I'm constantly changing.

tbh i would just get moetes adapter and have someone burn you a chip, pretty easy as im guessing you just want a basic stock chip as it was.. benifits to this way are cheaper as well as you will be ready for future mods or changes from simple such as fan on/off temps to complex such as major engine mods, oh did i mention cheaper
I would also think that anyone with dyno tuning or has the capability to data log would have the equipment to flash the EPROM so what would the benefit of this be?

Have you seen one installed? I haven't. I have the multiple program adapter for my Powerstroke and it sticks out of the ECM a little. He custom made it for DP-Tuner, I think since he won't sell it except to DP-Tuner and refers all calls to them last time I called.

One more stupid question. Can I datalog with my current chip, email the results to you, have you send me another EPROM and re datalog and send you back the old EPROM?

yep i have seen them installed as i have one, the one ****** shows will fit under the cover, the one i have has the zif so i use longer screws and put cover on with slight gap, and for multiple tunes moetes has some switching ones, no changing chips just turn a switch to the tune you want.. very slick and handy

Pretty slick. Just curious. I could see it if you wanted to run multiple tunes like a race tune, street tune, etc, etc.

I really enjoy helping those willing to datalog.
I've always used DataMaster, but recently learned that TunerPro has a better Histogram, so if you or anyone can teach me I would be greatful.
I'll send you an adapter for free. When we nail it, you send it all back, and I burn the final into your memcal.
Call me and I'll work up a file on you!

I have to assume you're running someone else's program. I can't modify what I don't know. This is why we start with the adapter. I'll need the answers to the 14 questions found here:

Aklim, I have a ribbon cable plugged into the ECM and my chip is on the dash with a ZIF adapter. I swap chips at the track. IF I ever get it perfect, I will put 2 tunes on one chip, with a switch and get it all back in the ECM. Crappy pic.

Sounds like a relay sticking. The chip doesn't have any moving parts. It's just firmware.
