Saturn Ion Map upgrade

[mac99]

I'll be tuning an o7 saturn Ion Redline SC car this week. Would it be best to purchase a 2 or 3 bar upgrade to tune the car? Is this even available?? I want to tune the car for race conditions. Thanks

I don't think there is any computer upgrades for the 4 or 6 inlines. Also your post doesn't make since, they don't have an 07 ION Redline, and the MAP is already set at 2 bar. Tuning these cars really doesn't have a difference between race and street, except for tuning for racing you don't have to worry about tuning stuff like Idle since the car would only be idling before and after a race and hauling.

You should get to know the PCM before jumping headlong into it with high expectations.

Good luck.

you dont need a 3 bar on lsj's even with 20 psi 2.5 bar. the difference is more in maf airflow tuning or speed density tuning opposed than spark tables after 14.7 psi. since our timing is based on grams a cylinder.

minor correction - there ARE, in fact, '07 Ion Redlines...'tis their final year in existence :cry:
