1993 Nitrous tuning

[JKDZ28]

I'm new to nitrous guys, I just had my PCM upgraded by Alvin for my T56 conversion.

Will I have to have a different tune to run nitrous? Or will my basic tune for NA be oK?

BARE with me because I'm new to nitrous, just a question I've been pondering.


thanks in advance guys

I am no expert, but I am sure he can make a chip to pull timing at higher RPM's. Either that or a Digital 6 Box. Or a LTCC conversion.

[JKDZ28]

yea the MSD box is def. on my list

can you use the box to retard timing, I'd perfer not to have timing pulled perminatly for daily driving

[BaddAss93TA]

yea, your gonna want a new tune. he can hook you up with one no problem ;)

[JKDZ28]

for the tune.... does it affect N/A performance?

Considering I won't be spraying that often... I'd perfer not to lose HP by perminately retarding timing

[BaddAss93TA]

well you could always get two chips done and jsut swap them when you hit the track

[JKDZ28]

hrm... interesting idea..

can you retard timing with the MSD box?

[SWINGRRRR]

Yeah. The MSD has a built in dial.

With the Digital 6+ you can set it up to retard with nitrous. That way you don't have to get a new tune.

I also reccomend a digital 6 box. If i pull the itming out of the chip it will run worse NA.

[JKDZ28]

Thanks guys...Yea thats my reason for not wanting timing pulled for N/A performance

This is exactly what I did when I was running a OEM PCM...worked like a champ. Alvin made both of them for me...

So... If I bought a MSD box would I still have to have 2 different chips?
