Friend of mine said his stumble got worst when it lowered RPMs of the changeover, and a couple other small things.
Was wondering if anyone else has had any problems with the rtek 1.5 or 1.7?

 

Your friend sounds like he has grouding issues.

 

double ditto the grounding issues.

 

mine works fine but i do get a hesitation around the new lower secondary staging point at times. when i'm wot the secondaries come on fine. but when i'm cruising around 3400 to 3500 my car stumbles sometimes. 720s are brand new and i'm going to clean the primaries to see if it makes a difference.

 

you can tell when the 720s come on but by no means is it a stumble. Mine works just fine.

 

Grounding issue if you are getting the hesitation when the 2ndaries are coming online.

 

so other than that, no other problems? awesome!

 

My 1.7 works perfectly!

 

Got a 1.5, no problems.

(Wish the 2.0 would come out VERY soon.)

 

1.5 here to. Works Great!

Wish they would come out with 2.0 also.

 

is there a projected release date for the 2.0? i want to upgrade to get rid of my fuel cut but i don't want to send in my ECU if they are going to release an update soon.

 

Can you run stock primaries 550cc and 720cc secondary with the r-tek 1.7 in a 87 t2. And do you need a safc to. Tony

 

sounds like you need to do some reading up on the chip go here www.pocketlogger.com and yes the 1.7 chip is made for the 550 and 720 combo

 

Sorry misspoked do you have to run stock primaries 550cc and 720cc secondary or can you run all 720cc or bigger in both. Thanks Tony

 

As suggested, go to www.pocketlogger.com and READ the info about their ECU upgrades...

That isn't too hard, is it?

 

After my 1.7 chip was installed, I had all kinds of problems with idle and surging. Ran way too rich. After asking for and following advice from fellow forum members, I grounded and grounded. Still had an idling problem. Found a cracked turbo snorkle. Got if fixed. Car runs better than ever. I am extremely pleased with the product.

 

Hay bud thanks for all the help, couldn,t of done it with out you.

 

I'm about to run the chip with 720primaries and hopefully if the injectors ever get to me 890 secondaries with a bnr stage III turbo. Now of course it is going to take some tuning but it is still good for retarding timing etc...
